I keep an eye out for the late 1980s Deore XT, DX, and LX product line. I find them on donor bikes or at co ops. Last upgraded my 1988 Cimarron with a 1990 Shogun Prairie Breaker donor bike. It was full Deore XT. I. have since changed the brake calipers to Pauls that came off another donor, and changed the levers as well. The Cimarron started as a $15 garage sale bike in slap wore out/deplorable condition. Still has original paint with my noticeable touch up work.
