In this price range, a few hundred bucks shouldn't be a big deal- you're spending upwards of $8K, possibly more depending on what you need to spend on electrical, site prep, etc......
Find out at least what this less expensive dealer intends to do for delivery- will he charge more because your're farther away than the customers in his service area? Will he get someone out to you should you need service, and if so, will there be a trip charge for the extra distance?
I'd imagine that the close by dealer, should you call them, might not go out of their way to help you, especially if you bypassed them for another dealer.
All over a couple hundred bucks?
Absuolutely check out other brands too. You shoud be doing this anyway, to better your chances of getting something that's right for you.
Don't get too hung up on money, though.
