I'm sure no-one will want to do what i did because it doesn't involve titanium or brand names.
BUT here goes.
i got a 1mm neoprene wetsuit and a 3mm vest. total of $70 from a non branded factory outlet in adelaide.
the 1mm of neoprene keeps me warm because i spend most of the time above the water (i'm not that good, i just don't try very hard

)and the wind chill is probably the coldest thing. I use the vest if it is particularly cold.
I find the combination of these gives me ultimate freedom of movement for putting the board back on and keeps me comfortable.
If you're not fussed about displaying your coolness by wearing a brand-name i would reccomend this option.
