Sorry to hear about the arthritis.
I play both upright and DB. I have a Veillette fretless and it's a really nice bass. Strung with LaBella black flat tapewounds, you get a sound that is very good for jazz. I can't say it really duplicates a DB, though - not the same initial thump. Oddly, in the one band where I switch basses around, the band says my Fender 51 RI P with Chrome flats sounds a lot like the DB. So go figure.
