well, i would say RCmod but i may be biased.
RCmod offers this:
returns - 100% money back guarantee!
shipping - 2-3 days priority mail.
prices - always cheap because they buy too much.
service - they do it cause they love mini rc and not so much for the money, so they try really hard to please.
quality - they tell you exactly what you're getting.
i can't speak for QFM, but this is what RCmod offers. if it's something that TinyRC sells then i suggest you buy it from him. if he doesn't sell it, order and see. shipping for orders under $10 is only $2 at RCmod.
