I have been researching the same thing, still haven't decided but here's a little info.
CPP: The deluxe bar will fit and the lowest price (Free shipping through Summit)
Porterbuilt: I don't think they sell one any more. It's not on their website.
No Limit: I think they give a discount to forum members and I'm guessing their customer service is far better than CPP. I also like their shock relocation kit, and I don't think it will work with the CPP bar

If I do go with the CPP deluxe bar, I think I will try this shock relocation kit
