I say use Bart at bigboyhobbies. I was reticent to spend the money on my recently purchased 3030 from him. He answered all my questions via email and on the phone thoroughly. And believe me I had asked a lot of questions. He is very easy to get a hold of and even answers his emails on Sundays. Shipping was fast. I ended up getting a pin pointer from him as well. I asked what the guys were using and saying. He steered me away from the more expensive one and to the one he felt was better. My hat is off to Bart. Keep up the good work.
