Phillip *and wife Kaye* Deal make an excellent product. Custom made for each build - some FFR's have high back seats, some have classic, some have dual bars, some have the single roll bar. The thing to be careful with is the seat measurement if using a high-back seat with a sliding rail. There's some wiggle room I suppose but mine is fixed so it's not an issue in my case.
The cost is well worth it IMO. If there is any drawback, it's the fact that he uses some fiberglass or plastic poles in the center (so it doesn't droop). It means you can't fold it. I roll mine up and it kinda looks like you're carrying a rifle.
