Boardgameguru for me. They were set up and are run by one of the guys at the London on Board meetups! He saw that there was a market, and now makes a living from it!
As for people requesting games, I wholeheartedly recommend Galaxy Trucker Anniversary edition! (If you can find it, I think they are doing a second printing of it soon)
In galaxy trucker, you have a ship:
And you have a pile of components:
Someone says go, flip the timer over, and you have to grab a component from the middle of the table, look at it, and either attach it to your ship, or put it back on the table face up, so anyone can see and take it. Eventually you either finish your ship or the time runs out, then you have to fly it around facing enemies taken from a deck of cards (there's something like 30 cards per round deck, you use 8 cards from each round deck each game, so there's enough that there's a good variety. And then you hopefully make money, or at the very least survive. At which point you do it again with a bigger ship!
