At first when I switched to Sky, my area were having problems causing my connection to cut out every few hours. It's stable now though, and I'm getting 2.7Mb down with 768K up (I always get these speeds) - only £10 a month as well. My download may be slower than what my Virgin Media connection was (which was 4MB), but it's the upload I want the most as uploading many music files to my website takes far too long on 400K.
Initially I wasn't pleased, but now I am since everything is working
