in my opinion, there are no better prices and service on tamiya stuff than RC champ. try again and you won't regret. Only drawback is that you have to deal with them through email and wait sometimes a while, but it is because many of us are ordering..... Everything else is perfect. And there is a bunch of people throughout the world that can backup them on reliability and good service. Check around the forums and you will see only good comments. I'm a converted...
other good fella is andy from hobbymania.com.hk. Very good service as well. Check his forum and drop him an email.
precisionrc and rc-mushroom are also Ok. haven't had any complaints.
rc-mart, I initially order some stuff from them, but shipping is expensive and now, only when I have a bunch of people ordering with me (or is stuff that only they have) I go for it. otherwise, any of the above stores can do it better, in my opinion.
cheers,
