Ford F150 - Rollpan options

I'm having my 2001 F150 fleetside repainted soon and I would like to install a rollpan on my truck and have it painted as well. I've done some searching for rollpans online and have seen a lot to choose from. I've seen some that are steel, fiberglass, and urethane. I think steel would be the most durable, but most expensive too The Sir Michael's roll pas include some "end caps" that are supposed to go somewhere. Stylin Concepts sells some that are urethane. Any thights about those? Anyone have any opinions? Pics would be nice too.
Thanks!

I've been thinkin about makin my own roll pan, being that there so expensive, i could probably make one look just as nice as any, i guess? If i end up doing it i'll post some pics.

The sir michaels end caps have to be welded on and fit to the vehicle would take some experience with body work to make it fit or a body shop, the fiberglass and urethane ones are paint and bolt on, I have the urethane one from street scenes
