Another consideration is that I don't like supporting those who don't contribute to the sport. Steve from Speed Tech does, he promotes and participates in this hobby himself.
Don't buy from places like tower even though they have descent customer service. Companies like that could careless what your buying as long as you're buying. Buy from your local tracks or shops if they do a lot to help the RC sport grow. It makes it so that more tracks available for us to go race and practice at.
Any one of the advertisers here are highly recommended. Most of them stock kits, and from each and every one you will receive (in my opinion) superior service to some of the bigger places like Tower or Horizon.
Not to mention, better prices...
