Buying a wetsuit is next on my "to do" list.

I have also heard very good things about 2XU. www.Trisports.com will do a good job of fitting you over the phone and is very good about returns.

I also heard good stuff about Promotion, for the price point. Although, some people said they were "clunky"... basically meaning thick and a little hard to swim in.

I am leaning towards getting a really nice wetsuit. Swimming in a HIM or an IM in a cheap wetsuit might be torture.
