I think a triple gives you both range and a lot of gearing options. The big chain ring on that set up is 46 teeth, so you might be lacking in the high end.
That's a really old system, and looking at some comments, there may be some issues with the front derailleur, so definitely try riding a bike with that on it and shift it through its ranges before you decide to buy.
Can you tell us what bike you're looking at with 7 speed RSX? RSX was 8 speed for a couple years, then was replaced by Sora.
Not the OP, but I scored a used bike with 7sp RSX for $60 once. A 1999 Diamondback Interval. The one I got needed some shifter flushing and freehub flushing and repacking all bearings, all shifter cable housing needed replacement, still a good deal.
