I've bought a Trek 750 I bought in '93 and still love it. Did 15 miles on it Saturday evening. Changed the shifters last year and just upgraded the rear derailleur from Altus to Alivio last week. Had a little trouble on that upgrade, I posted in the bike mechanics section, but lengthened my rear cable housing and it shifts great now. If it's in decent shape, should be a good buy. Price would depend on shape, my 750 was right at $500 ('93) new, the 720 was one step below it. Good luck
