Tried the X-Rays myself, even a 415MSXX but am back to a TA-05 now, and you know what, on most club days I'll be inthe amain amongst a sea of X-Rays and my parts are half the price.

I had an X-Ray once, but I couldn't afford the payments on the parts!

And Tamiya bits are usually the easiest to find in Australia. I can name 7 or 8 online stores that do Tamiya Parts, X-Ray maybe one or two.

The X-Rays are nice for bling / show and if you're hardcore, go for it, but a good driver in a TT-01 Tamiya will still beat a bad driver in the latest X-Ray perfectly set up.
