Hey you guys up there in Canada eh - last month, I went on a dive off Palm Beach, Florida. Two out of the six divers were wearing drysuits in 72° degree water. Looking around, I have found some pretty nice drysuits in the $100 - $200 price range. I just sold a like-new Bare on eBay for $370. I'm not sure what your budgets are, but I sure couldn't face that kind of cold water you have in the summer, much less any other time of year.
I'm not familiar with White's wetsuits, but they're drysuits are well-made and pretty good values for the price. The turnaround on their service is a little slow though - some folks have waited a couple of months for repairs.
And Daval - if you do upgrade later to a drysuit, then you will have to factor in the cost of buying the wetsuit also. Easier to just buy it once.
