Here's another brand to consider, Pro-limit. I have the global series one.

I think getting a really good wetsuit is worth the money, imo, for two reasons.
One is that if it is more freely moving and keeps you warm, you will have more fun, by far.
The other is that if it is well made, it will last several seasons, ultimately paying for itself by not needing to be replaced.

If possible try on a few and make sure you can move around moderately freely in it. Nothing is worse than using up all of your energy just pumping up your kite because your wetsuit makes any movement a workout. I use to get worn out just walking to North Beach from the parking lot in my old wetsuit.

Getting a hoodie to warm your head probably isn't a bad idea either.
I tried to find the reference page on the O.R. site, this is as close as I could get. It's the thing on the maniken's head in the picture. It's called a neo cap and is about 18 bucks.
