The Best Website for Sit & Go's?

In the last four days I have decided to return to the poker world by playing the speed, NLHE $6 S&G's on partypoker.com. For many of you $6 may sound like loose change, but to a skint student it counts as quite a lot! Although I have been successful so far I'm slightly resentful of the partypoker website for three reasons:

1. The exchange rate from £s to $s means I'm getting a bit screwed on the deposit/cash out divide as the website appears to be skimming a fair bit.
2. For every sit & go I play a 6th is raked (i.e. $1 of $6). This adds up after a while and although I expect a rake to exist, this feels like too much.
3. Their loyalty points system is hopeless. I have played over 200 games in the last 3 days (so that's about $200 from me to them) and yet I haven't received any increase because of their stupidly designed system.

However, I do like some aspects of PP. Because it is very popular the tables fill up quickly so I don't have to wait for too long. I love their speed system because the blinds go up appropriately fast, allowing for more action and bluffing and as I have gone from a $50 initial deposit to $480 in about three days, I can hardly complain that the system isn't benifeting me overall.

My question is whether there is a better website for my style of play out there? Ultimately, I'm looking for 10 player sit and go's, no more, no less, with speed blinds, pounds as the currency and a good loyalty system with plenty of promotions. I'd appreciate any advice that you guys can give. Thanks.

While I dislike the new rewards program at ultimatebet (some others seem to like it however,) they have turbo and ultraturbo STTs at $.50 and up all with 10% fee, and have 2, 6, and 10 for STTs and some larger field sitngos but those tend to fill very slowly in my experience. It's also not very good for sitngos other than NLHE.

Stars is good for Sit and Go's...Never had a problem etc
