I've always been a fan of the Vlocity man, i always liked it, but like you said, its old tech...
I mean, there are bids on ebay for rotors, you could get luck and get one for a really low price... The vlocity is not easy to disassemble or to assemble, you also need a screwdriver, so if you are out there playing around and a ball breaks inside the loader, you are going to spend some good time trying to clean it...
Back when I had one, paintballs broke a lot (mostly because paintballs at the field were pretty crappy), so i would lose the screws when cleaning it up, which is a real pain...
I mean, the loader performs well with the board, but if you have some spare cash around, try getting a new loader, if not... Its a good loader either way, i just hate when it comes to replacing batteries or cleaning it... lol...
