I agree
I have a venture with an 8103 and it was very easy to setup, however, I have built and flown 3 other helis.
I try to support my LHS whenever I can but if there is too much a difference in price, (like in your case), I usually go the mail order route. Fortunatly for me, the shops in my area have very good prices so it is usually not an issue.
As for help in setting up, I would look for a club in your area that can help you. The LHS is great, but if they are not out there with you when you fly, then you are screwed. You need the support of other pilots to check things out, help you make adjustments (at the field), and help you when you're flying.
Only two constants when you fly helis:
You'll have a blast.
You will crash.
Best to have some help when you do both.
Jim!
