I decided to go the budget route with my Zam, as well. I ended up fashioning pretty much my entire costume after the 12-inch doll, and I liked the fact that I could examine the details up close and rotate it in my hand. It's a bit more simplistic, and I used the vinyl and pvc also. I don't think I spent more than $200 on the entire costume.
So, it's not a "screen acurate" version of Zam, but I'm happy with it. I've really enjoyed making it...and especially wearing it to my group's events. =)
Also, I really get a kick out of this site. I've gathered a lot of useful information from this forum, and I like watching the progress of all of the different Zams. All of your costumes look spectacular! And good luck, Cressie, on your budget Zam. Can't wait to see the finished product.
