Beware, not all lugged bikes are of any quality. If its a heavy bike, its possible that its made out of really cheap tubing, lugged or not, and isn't worth its weight in lead. Also look at the dropouts. Are they a good 1/2" thick or so like many road bikes have? Or are they 1/8" steel plate? That will tell you alot about the quality of the bike. If its a good frame, and its straight, have fun!
