hi,
i have made several orders from this site www.superfastrc.com
i got all my orders within 2 days and the shipping was free by priority mail (i think that the shipping is free over $50 or something like that)
they carry mostly xray products as far as cars and trucks go and stock motors. the lipo's are cheaper than any place i have found. they dont carry brushless motors though, the best deals i have found for that has been www.b-p-p.com
and for misc odds and ends i look on www.ebay.com

have fun in the hobby
