I have a Collegiate Graduate with the EZ change gullet system and have been very happy with it. Right now it has the extra wide gullet plate in for my wide quarter horse. I have changed plates and used it on different horses with good results. My trainer hates Wintecs, but I sat on one in a tack shop once, and it sure was comfortable!
If you have a good idea what you want and don't have a lot to spend, you really should try e-bay. It's kind of hard for a saddle, since you can't return it, but with the EZ change system you should be all right. And definitely for a bridel. I'd rather get a good used bridle from e-bay than a cheap new one. the cheap ones are like cardboard and you can never get the leather soft.
