I can guarantee that it's impossible for any ISP to offer an uncapped 40Mbit connection for £22.50 pm. That's a theoretical bandwidth of 13TB per month. They'd be losing bucketloads of cash if you did that - that kind of bandwidth costs _thousands_.

This is the problem AAISP have. Everyone else promises things they can't deliver, for absurd prices. Someone comes along with a moderately sustainable pricing model, and suddenly they're expensive.
