Housing suggestions for Canon 5D Mk2?

I am looking to purchase a housing for my Canon 5D Mk2 and would greatly appreciate some expert advice prior to "taking the plunge". If at all possible I'd like to keep the purchase in the $2,000 range (or below) and so it seems that Nimar and Ikelite are the only options. Are there others?

I intend to shoot primarily video, is there a best all around lens for this?

What are the best settings for video? Neutral? Faithful? Cinestyle?

Any and all other suggestions are greatly appreciated!!!
