I'm doing a shower with another system: Kerdi. It's sold by schluter systems www.schluter.com
I really like this system for a couple reasons:
1) You can pick and choose components. You can just get the waterproofing membrane and make your own 'mud' floor', or you can use their presloped tray and membrane. They have trays that come in 48x48 or 32x60.
2) The Internet support for this product is unparalleled. Schluter has videos and all kinds of manuals. But even better is Johnbridge.com. Check out the forums there for tiling a shower. They've really took all of the intimidation out of this daunting task for a diyer.
