It's all Red Eye Glass (even the stuff that says GEAR, it's not the German GEAR) which is a great glass company, I just got a new zong from them. I'd recommend the zong, just because I like zongs, but number two and three look pretty cool too.

For around the same price, you could get a Ehle German glass on glass diffuser bong with shipping included. http://www.showmeglass.com/Waterpipes.html
^This guy posts on Cannabis Culture and is a highly respected glass blower there, he can definetly be trusted.

Also, if you like any of the Red Eye Glass stuff from rollies, I can get you it for cheaper. For example, link number 861 for $90 USD I can get you for $85 CDN if you'd like, possibly less. Talk to my friend The Bongfather http://www.thebongfather.co.nr/, he posts at Cannabis Culture and just recently did a pipe auction for charity. If you are a member of Cannabis Culture forums or just an avid member of cannabis culture in general, he could probably give you a 30% discount.
(his site looks pretty sketchy, but I assure you he is very legit)

Peace out!
