About what I paid for my 1997 Wave last year!!!http://www.nrsweb.com/shop/product_list.asp?deptid=1174
I originally got mine for white water kayaking. But it is AWESOME for sailing once the air/water get chilly!
Nothing like being totally warm and dry all day even when you dump it!
May be better deals elsewhere...but this gives you an idea! Non Breath-able versions are loads cheaper but I would not recommend them as its like wearing a rubber rain suit. My goretex Kokatat breaths well and you don't get clammy in it all! I would suggest a relief zipper, and built in booties!!!
Kokatats are high dollar...but their company backs them VERY WELL.
I just sent my 10+ year old suit in and for 20$ they will pressure test it and fix any leaks. If its deemed to have the laminate broke down they will send you a brand new suit! Basically a buy it once for life deal. The only wear items are the gaskets...but with some 303 applied now n then mine lasted 10 years before I had Kokatat replace them.
