Door/window seals

I need to replace a lot of the rubber seals on the doors and front door windows. I'm finding replacements sold by Steele Rubber and Dennis Carpenter. Curious if members have any experience with either of these and how they fit, ease of install and longevity. Or if you know of another supplier for these please make it known.

Mac's is off the list for me as they have just resold Dennis Carpenter's parts at quite a markup!  

Thanks

I bought all my parts for my 65 Econoline from Dennis Carpenter when I built it about 20 years ago, had the van repainted 3 years ago and reused all the rubber seals in the doors and windows. I bought some body panels for a 59 Ford station wagon from Macs and I was pleased with them as well.
