Everything with Minolta stamped on it works fine, even old lenses like the 70-210 F4. Peace of mind there. As Ronin says, take your kit to Jessops and try it - you don't have to buy it.
Personally, I thinks it's not a question of an upgrade, it's more of a switchover to modern technology, and it's a must. So long as you've access to a PC and decent image editing software I can think of very few reasons to stick to 35mm film anymore. I say this becuase my D9 went bye byes today (alas, but it had become pointless, heavy baggage) and the only film camera I'm keeping is the cheapy Dynax 60 - becuase it's worthless anyway.
