I mean.. if your giftcard must go to your desire for a fretless, I'd vote the Squier.
I'm looking at Thomann and they've got a much better selection to choose from. I'm curious how those inexpensive Harley Benton's I'm looking at play.
As far as sight unseen, out of the 3 basses I currently own only one of them was hanging on a wall in a store. The other two were sight unseen, one from Sire USA (My P7) and my most recent addition from zZounds.. and all three of my basses are kind of special to me at this point.
Not long after I got the Sire, I also ordered my first fretless.. in the $750 price range, and it had a unique feature set.. was a nice bass but the right instrument to adjust to fretless on for me. I owned it for a year, and took a $275 loss on a sale after having it listed for several months. While I didn't play it much, it was cheaper than renting the same bass for a year.. and the sale funded my the new guy in my lineup who has quickly become my favorite.
The two I still own that were sight unseen, I had a very strong inclination that I wanted them for their specific feature sets, and listening to youtube videos. Couldn't be sure til I got them in my hands.. but even if I hadn't liked them, it was worth the cost of shipping to try them out for 45 days imo. So far, I haven't returned any, other than one replacement due to manufacturer defects, which was hassle free and I had the replacement 2 days after I dropped the defective bass off for shipping.
Being honest though, a lot of that confidence comes from dealing with music equipment retailers. The idea of shopping for instruments on Amazon makes me weary. I don't know their policies, however.
