I used to have the Tomy NSX-R. Sold it, then got one of those "Rally Racers" from KB Toys for xmas. I like the buttons on the Tomy-type models better, but the antenna on the RR is much better.
Lol, don't know how that relates, but I don't see why the "Tomy" and non-Tomy's would be any different.
As was stated in "Armageddon" -
"American components, Russian components....ALL MADE IN TAIWAN!!!!"
