I asked the same question in a thread a few months ago about TGC, have a search through old threads, I got a few responses, they were all positive I think but check back to be sure. I emailed them a couple of times and was impressed with their polite and businesslike response.
I was thinking of doing my IMC there (fast track), still am - but am under threat of redundancy at present, so it'll have to wait but will be interested in any further posts for the future.
If you do check them out, would you post your reaction or PM me if you don't want to post.
