Some dealers are OK, others do a lot of lowbrow tactics. So far, the worst I encountered was a dealer demanding I sign a non-disclosure agreement on prices given, I declined, and he gave a "discount"... the dealer had their own MSRP, and was offering to sell at their "cut rate" price --the factory MSRP. I thanked them for their time and scurried out. Manufacturer direct is always a lot nicer in cases like that.
Sportsmobile is always tempting for a "B", because their prices are competitive... but you can really rack up the price by adding accessories.
