Carpet replacement '90 F-450

I'm looking to replace the old rubber mat in my '90 Super Duty with a nylon carpet. It's a diesel and naturally noisy. Looking to cut down on noise if possible. Have been eyeing one on E Bay from 1A Automotive but sounds like it might be not top quallity (only $99.95 with shipping, I think). It does cover the full floor right to the back of cab, so it says. Any one have any dealings with this outfit or any other options or suggestions? Thanks.
