Everybody has their preferences. I have personally dealt with QUANTUM in Shelbyville KY and really like their service. They are about 75 miles away and I drove there one saturday and checked them out. Very good selection of engines, kits, ARF's, radios, and accessories. I just have them ship everything to me because it's cheaper than driving there. TOWER HOBBIES is also pretty good and anything else I need comes from the LHS in Lexington KY. Happy flying.
