You might try checking with these folks, http://weavermodels.com/ , they do TMCC/RS installations and if memory is correct they more or less took over the retail end of TAS's work. I believe TAS is still in business, just not in the retail/consumer end.
Forgot to add that Weaver is in the 2 & 3 rail "O" business but they might be a good starting place for your decision making process.

Back in 2005 / 2006 I purchased some USA 1/29th scale locomotives with Lionel TMCC R/C supplied by Train America Studios. With TAS gone now has anyone stayed with TMCC in G scale? I am trying to decide if I should use it in my Bachmann 1/20th engines or change everything to something else.
Thanks
