PSU1980, I second your opinion on the MTHRRC. It is a very good deal, you get the yearly car, discounts on products and special yearly products at very low prices available to club members only. Very good deal. And they mail you all the catalogs.
They also have a membership with the same benefits, but no yearly club car, for either $20 or $25 a year (forget the exact cost on that one?). There are RK, Premier, Tinplate, HO, S and maybe some other memberships at varying prices listed in the back of the catalog.
