Shopped at these online stores?
 

I'm looking to buy the new Nuvi 750 that Garmin is going to release and I have seen a few stores that have it selling for less than 500. Most places seem to place it at 600. Have you guys used any of these retailers before?

megagps.com
emarinesupplies.com
fotoconnection.com
ambientweather.com

Also, are there any recommendations for cheap price and reliable retailer for this product?

I havent shopped at any of the stores listed. You should definetly check resellerratings.com. The last store listed ambientweather has a perfect 10/10 rating, the fotoconnection has a very BAD rating 4/10.
