There's a megathread on these on the DB side on the front page of the EUB category. It is a couple of consolidated threads so it seems a little schizophrenic.

You cannot bow them - the radius is flat like an electric bass. They are uprightified fretless electric basses, not electrified double basses, so they're not much use for transitioning to double bass nor do they sound extremely like a double bass.
Their highest and best use is in a situation where you'd be playing fretless or rock/pop but want the cool factor. Run it through a sansamp and you'll get a very nice rock/pop sound out of it. I used one for a while in an "acoustic" trio that covered rock tunes and was amplified and it was a great fit.
So, with a sansamp it would actually suit your needs pretty well: people in church would love it and you'd no longer be bored playing the simpler bass lines. You can pick them up used from time to time for about $250-$300.
This is a good post to remind people on the electric side about this, because it is really more of an electric than anything else. Consider posting any specific questions in the megathread to keep all the information in the same place. It gets bashed pretty hard in the megathread because people are comparing it to EUBs, which it's really not. It's its own animal, at a much lesser price. People who need something that sounds more like a double bass and that can be bowed get different EUBs starting at around $1,500. There's a ton of info on those on the EUB page too.
