I have a bsx upright electric as well a a 3/4 double bass of unknown origin. The upright electric gets a lot more use since it's a lot easier to transport and really doesn't sound that significantly different once the sound makes the way through the amp.
The upright electric is easier to play as well.
However the acoustic bass is a lot more fun to play...
It hasn't been that hard of an adjustment for me, but it did take practice and work. One thing I did was put little "fret" markers on the side of the bass strategically so I knew where to go for best intonation. They are still there but I don't have to pay much attention to them anymore.
I say go for it!!!
I will also not let the price tag limit your thinking. My double bass cost me $500 used and it records fine and plays fine. I personally think it's better to get something cheap and playable and see if you like it enough to keep it. I think people want you to spend a lot of money to get started when it's not really worth it IMHO.
