As for dry suits definitely horses for courses, I know a lot of people who use Otter and they are all well satisfied, personally I would recommend an Aquatek (not to be confused with Aqua-Tech) from Aqualeisure Watersports 01745 815476 but possibly they're a bit above your budget from what you say. Whichever one you get go for the made to measure option unless you're the one person in a million who is an absolute stock size.
I also use a Weezle undersuit and definitely give that the thumbs up as well.
