I have an acoustic/electric bass uke from Rondo Music that my wife got for me for Christmas that I'm quite pleased with. My understanding is that they're getting them from China and doing basic QC and setup. Mine had a little bit of fret buzz on one fret that I took care of myself, but they have a reputation for good customer service, so I would be comfortable buying from them.
Also, FWIW, the pickup/preamp that came installed on my bass uke is very good (sounds great plugged straight into my amp) and can be had for cheap on Amazon. Cosmetically, both of these are identical to what I have: http://a.co/fPAtTyu and http://a.co/dItpM2f although it's hard to say that they are identical internally, but it's so common for cheap electronics like that to be sold under 50 different brands that it's likely. So pick up one of those and a $30 uke and you've got yourself a good weekend project.
