Darrell and I will be in LV in a month or so...and I have definite plans to check out Fry's Electronics (S. LV Blvd, past the airport) for the same item you're looking for. Check the LVRJ newspaper for the weekly ads. Fry's sale prices are very comparable with Amazon,Buy, etc.
If you order off the internet, make sure it comes with free shipping.... sneaky shipping charges can wipe out any savings
Lately I have been checking the product reviews on Buy.com and Amazon.com about items that Fry's has in their sale ads, very educational.
