Hey NiceWife, welcome to TB. Now we get to hijack your thread and argue about everything that anyone says about an acoustic bass! Or anything else!
A couple years back I bought an Ibanez AEB10 (4 string, in your budget). It is nice for being able to pick it up and quickly work on something without having to set up any gear. It did not work out very well for my bluegrass group (too much sustain, I ended up with an EUB which works well). It also is handy to take on trips, vacation etc. so I can play away from home. I've taking it camping a couple times and while funner than nothin it is not loud enough to really use unamplified.
If I had to do it again I would look seriously at a Gold Tone instead, would do what I use it for and the travel part would be easier. I've heard that one should stay away from the fretless Gold Tones, U Bass, etc. as the scale is so different they are hard to play with any degree of intonation.
I totally agree about getting a Goldtone but I on the other hand recommend fretless for any of the Uke size basses or microbasses. I've had a fretless Kala Ubass for years and it was so easy to play in tune I brought it to a jam at a friends house a few days later and was playing Classic rock and Blues with no issues. They are a lot easier to play in tune compared to a standard fretless bass which I know sounds strange but thats my experience anyway.I had a fretted microbass that I couldn't get rid of buzzing frets on as well as the intonation being out quite a bit on the A string. Intonation issues plague many of the fretted minis. Some are good some are lemons. But which ever you get fretted or fretless if the intonation is good and you have a good setup they are pretty hard to beat. They sound incredible but you do have to plug them in for anything more than noodling around on the couch.
