I order mine directly from Mr. Graber. As far as I know he doesn't have a website, but he will send you a brochure with the info in it.
His phone number is: 812-636-7725 (home) or 812-890-6526 (cell). If you call the home number more than likely it will be his wife that answers but she can help you too.
I have a friend who has a Graber show cart for sale. It was used only once and has been covered and shedded since. I know he would take less for it than a brand new one. If interested, email me and I will give you his phone number. It's a top of the line cart.
Unfortunately I wont be ready to buy until my tax return comes back, but ill keep it in mind in case he still has it then. Would you happen to know color, stripe color, and wheel size?
Not sure on the shipping charges. I live close enough that we have just gone and picked ours up. I am sure if you give them a call they can give you an idea. I do know that they ship them. They are nice people.
