Theres threads about these on the TDPRI and also on the Squier 51 forum. Theres a guy on there piecing them together using USACG bodies and they look stunning to me.
I had thought of going the more budget route, by getting hold of one of those Jazzmaster style guitars that the likes of Stagg and Wesley do, taking out the p/ups, slapping a tele style neck and bridge on and seeing what happens. I would have to use a pickguard though.
