not sure what kind of cold water you are eyeing. for where i am (virginia), i kinda think there really is no middle ground. a 5mm full would be sufficient for only the warmest of water here, and that same 5 would probably be too warm in the carribbean. i did my cert dives here in 2 layers of 7mm + hood, still cold as balls
otoh, it was like $5 a day to rent a wetsuit on my last vacation... financially thats like 40 days of diving to recoup the money. it would take me a few years for that... if the suit even lasted that long. of course there is the whole personal comfort aspect too which definitely plays a role.
i dont have any real suggestions on brand or anythign... i just know what i know from asking the same type of questions around here...
