I hate that my first post seems like an advertisement of sorts, however - I found this forum while searching for info on a tonneau for my 02 Ranger Edge. Since I bought one, at what I think is a great price and it appears to be a great econo tonneau, I had to give it props. I wanted a cover for temporary storage (pimarily) but it had to look great and be cheap. I found all three.
Got it on Ebay from carmicdirect.com. Cost $140 shipped, was delivered in two days, and the quality/fit is perfect. It even comes with extra weather stripping to accomodate trucks without bedliners over the front of the bed (will come in handy when I add the bedcaps) any day now.
I gotta admit - I thought I liked those factory bedcaps but this tonneau (aside from the marks left uncovered that those factory caps made) looks great on the truck.
If you're looking for a cheap tonneau, Trucktec is worth a second look.
