I agree with all that's been said so far, and also I've noticed that it seems people appreciate lugged steel, even on mountain bikes. It's not all that common to find a nice lugged steel mountain bike, and the quality ones I've seen are the ones that bring fairly high prices, as far as steel bikes. There are exceptions, of course. Your Redline looks very nice..........there was an old Bianchi Grizzly recently on e-bay, nothing special really except it looked to be in very good shape and had a beautiful lugged frame. I bid on it, but the price quickly went too high for me-
