I have seen the cast CLW H16-44's, my brother has few of them; they're nice if you have the chops to machine, mill out some detail etc. which of course Bob you have. The Lionel versions are VERY nice looking though (especially that factory LI "Dashing Dan" scheme in the grey and orange WOW!) but I'd probably still go with the CLW too.
The only scale-ish 3R road switcher I really pine for, to acquire and convert to 2-rail is that MTH Baldwin AS616. Oh yeah......
