I been using this HD dealer down in Florida called Brandon Harley-Davidson Buell Shop in Tampa. They go by the teamh-d on ebay, even their ebay stuff you can talk to get to get a better price.
Shipping is very quick. Figure out what you want HD or aftermarket, get part number, give them a call/email - negoitate price.
They do 20% off, but they also offer free shipping, and high dollar items they sometimes do 25% off. With no taxes either, comes out as a very good deal, so it comes out to almost 30% off shipped. I personally purchased Supertrapp 2:1 for $530 shipped (lists > $700) and some HD bags MSRP $599 for $470 shipped and a bunch of other things shipped for my dyna.
The only problem is that with the good pricing, they don't do paypal, but they might, if they can add the paypal costs (it doesn't hurt to ask).
