Desoto first wave wetsuit 07 vs 08

I posted this in gear reviews, but haven't gotten any input so..here goes. I have the opportunity to buy the 2007 first wave wetsuit (around $350), but there is also a discount on the 2008 model (around $420). I have researched the technical differences b/t the years, but I am just wondering if the new model is worth the extra money. Any input would be greatly appreciated!
Thanks
