hey, i live in that area too of southern cali, san dimas. i've been to vip hobbies, covina hobby, elite, and pegasus. the guy i talked to at vip is kinda hpi-biased cuz he gots an hpi, elite was telling me both the ntc3 and the gt4 are both good, but he liked the gt4 better, and pegasus and covina didnt really care what i got as long as they got my money.
im still leaning towards the gt4 cuz more people say its more durable than the ntc3 and it does have the 2speed. its $300 at covina hobby too!! they're getting some on tuesday. $275 for the ntc3 at vip. i havent checked the prices out at hobby town or hobby world or the other hobby shops, but i'll call to see
. maybe i should just go to the local track in montclair to see what others are using and ask them. im still leaning towards the gt4, but i might change, you never know.
