We looked into selling Garmin, but the price you can buy them for at Wal-Mart or at http://www.gpscity.com was cheaper than the wholesale cost from the distributor. $376 is the cheapest I've seen the 530HCX
PC Nation.com has the best pricing and great customer service.. They have refurb units for 286.00 and offer a cheap three year warranty on them as well.
