Anybody using this search engine? It is pretty cool. Basically it compiles data from a ton of different sites and allows you to search for whatever you are trying to buy on one place rather than browsing multiple forums. So for example, if you are looking for a slug barrel for your shotgun, you just do a search on riverofguns.com and see results from ar15.com, ingunowners.com, and so forth. I like it, as it makes it easier to buy and also gives more exposure to sellers.
