The 7424XP is a better machine to the old 7424. However, with that being said, I'll tell you that I'm on year number 11 with my old 7424 and have probably a thousand hours on it. No problems whatsoever. I'm fairly sure you can expect that kind of performance out of the XP as well. Considering a used 7424 will set you back dang near what a new XP will cost, you can't really go wrong with either one.
