Bruce,
I have a VR1 that I am not ready to give up quite yet (sorry). If you do order one from Graham Industries, Might I suggest that you assemble it with small brass bolts as I did mine. I think Graham sells a bolt kit for the TVR1, and maybe for the VR1 as well. Looks IMO much better than the fillister head screws that come with the kits.
