I have used Simply Electronics in the past. While I didn't have any problems, I wouldn't necessarily recommend them. It took quite a while to ship, which for me at the time wasn't a problem. However a work colleaugue did want something quickly, then tried cancellling the order when it became delayed and had problems getting a prompt refund, he got the money eventually, but not as quick as he would have expected. Also, they give the impression it's UK stock on the website, but the long shipping times and other things suggest otherwise.
