I love older MTB's. They don't get a lot of love in this forum, but they are great bikes. The Bianchi you posted is on the bottom end of their line, but they used to use lugs into the early/mid 90's on their frames. Double butted Tange MTB tubing is pretty good stuff. $60.00 is a good buy. I'd stay away from the Nishiki. Keep an eye out for GT's All Terra models, Bridgestone, MB series, older Gary Fishers and Diamodback Apex and Ascent models. Even the higher Trek 850/30's are good bikes. Here is a pic of my 93 Trek 950.
