Engineered Vinyl Plank companies besides Lumber Liquidators?

I am going to be installing flooring in my concrete slab basement. It seems to be very smooth/flat. I have been looking at the CoreLUXE XD and Ultra lines from Lumber Liquidators. They really talk up the "Engineered Vinyl Plank" angle and describe why it's superior to LVT. Having someone come in and leveling the floor to perfection would cost me about $1600, so I'd rather use the thicker, more rigid EVP that can mask slight imperfections in the flooring. LL adequately explains that theirs will do this; other brands not so much.

We've narrowed down our style selections to a few from LL. But I'd like to do some due diligence into some other brands with comparable products.

Important points:

• Waterproof
• Good wear layer (> 20)
• Click install, floating
• Would like to stay under or around $4/sq ft (but open to spend more for a much superior product)

What other brands should I be looking for, or at least what terms should I be looking for in my searches? Is Luxury Vinyl Plank with a thickness of at least 7-8mm going to be the same type of product as LL's CoreLUXE offering?
