RestaurantReviews.info
This one is the best of the two, however can't see a high resale value. It is a nice name for developing, but would need constant updating.
AudioProducts.us
The name sounds good and it brings to mind of what one would sell from this site. Developement and or a quick sale for this is the best way to go. By the time .us tld's really get going on the aftermarket, many audio products will be combined into other
appliances,(cameras,phones,laptops,pda's) so that the market for simple audio products may be shrinking.
