I feel you, but I'd say that you have pretty good chances with a good elder. In the end, all renowned brands repair old frames of theirs, if you wish. On the other hand, a bike is meant to be ridden, to be alive, and less to hang to a wall, nevermind its heritage. That's a sad picture, if you ask me.
I will hang a Lobo and a works Super T to the wall, but only because they've been raced successfully from 1999 to 2011 and now they deserve their rest.
I know what you mean, it does seem a shame to end up on the wall however I'm not sure that a repair will do the job. It's not really cost effective either when you look at how much a new frame would be.
I'll be keeping an eye for another Tazer though, but a later one with the gusset.
