I didn't get to take a photo of the Greg Bennett Mini Corsair before I sold it, but this is what it looks like (not my photo):
From worst to best, combining factors like overall design, ergonomics, tone options, and quality control:
Samick Greg Bennett Mini Corsair MCR-1 - Tiny little thing that's very convenient, but a bit too small/light for average-sized adult male. The bass would move too much when you play a little harder, and it also had neck-dive. For the price the quality's great, but just not a good match for me.
Ibanez Mikro - A bit bigger/heavier than the Mini Corsair, so it's a bit more comfortable to play. PJ pickups have more tonal options too. It also has neck-dive (though other people's don't), and I had to use a string to tie to the headstock to keep it balanced. Recently I had to open it up to rotate the tone knob module away from the shielding paint because it was getting shorted out. Not as many options for strings as I'd like.
Fender Mustang PJ - Love the tone, but the neck-dive was severe (and I can't stand the giant headstock that's unnecessarily long, which not only adds to the weight of the neck but also bumps into stuff).
Ibanez SR650 - Nice solid bass. J-pickup's a bit noisier than normal. A bit heavier than I'd like at 9 lbs (I prefer 8 lbs or less). I wish the P-pickup was slighter further away from the neck (I prefer at least the distance of about 4 fingers' width, so it's more comfortable to do multi-finger snaps during slapping). Nice balanced with no neck-dive.
NS Design Radius WAV - The EMG pickup tone is very neutral, and for some it's a bit too sterile, but most people buy it for that unique piezo tone that's not like typical piezo tones (it has a huge bottom and does not thin out). You're not going to get a traditional tone out of this bass, so I consider it a niche product. Some might not like the one-piece bridge that doesn't allow individual saddle adjustments. Mine's 8 lbs., so just on the verge for me. Good balance--no neck-dive.
Ibanez SRH500F - Very simple and straightforward semi-hollow fretless, and sounds even better with La Bella black nylon strings (though make sure you get the 760N and not the 750N, because lighter gauge has too much upper harmonic noise). It's basically a poor man's Rob Allen. Mine's 7.3 lbs., and the neck is the very thin/narrow SR4 profile so it's very fast, smooth, and comfortable to play. It's probably the most comfortable of all my basses.
Ibanez EHB1505 - Great design (but taken from various other companies' headless designs) and the parametric mid-frequency sweep is much more useful than just a fixed frequency (and I wish there were two parametric mid-frequency knobs). Weights 7.9 lbs. for mine (some people's are even lighter). Quality control for this batch has been pretty bad though (multiple people posted about problems with their EHB model, including me), but fortunately mine only required re-soldering to fix. I hate the locking jack though--I have no use for it. Excellent balance with absolutely no neck-dive at all. One of the most comfortable basses I have.
Music Man Bongo HH 5-string - Very solid bass with great workmanship. Huge tone. 4-band EQ is one of the most flexible on the market. Mine was 9.4 lbs. so it was a bit heavy, but no neck-dive. The neck pickup is a bit too close to the neck for my comfort.
Dingwall NG-2 5-string - Excellent workmanship and oozes quality. Amazingly articulate tone. Nice 4-position pickup selector for tone options. Darkglass 3-band EQ is musical with good choice of frequencies. Pickups are a bit far from the neck so I added a Zero-Mod thumb-rest. But in the end, the 3-inch scale difference was too much for comfort and I decided to swear off of multi-scale and stick to normal 34" scale. Mine weighs 9.2 lbs, but it doesn't feel that heavy as it's balanced extremely well.
NS Design CR5 Omni Bass - It has one of the better electric upright tones out there, along with Takamine TB10 and Marco Marcustico, but it's a lot more ergonomic than those two. The Boomerang strap system is ingenious and very useful, allowing you to play horizontally and vertically, and switching is instantaneous. It was designed also for bowing so it's very flexible and useful, not to mention it has both piezo and magnetic pickups, so you can use it as both EUB and normal fretless. Mine's 7.2 lbs.
). Paid $40 for it and sold it for $40 in 1966.
