Flashkick, stop arguing man, you just don't get it. I knew I'd spark you (hence why I did it, pompous much?) if I asked anything gt related haha. You're right, the "price of a pipe cutter is NO WHERE on the internet" so what do you do? What you should really do is call the company. I really doubt you've got a legit price on a 21 ft pipe dragon, and based on your response I'd really doubt you personally would ever be able to find the real price.
The real problem as cobracommander pointed out is that people are too quick to jump to NS to solve their problems. If you've got a question (and yes, I assumed this was for some sort of assignment) its really much easier to call the company or email them. They will answer your question, and will be much more accurate than asking all 12 year olds of NS to guess a price or suggest advice.
