I am waiting for my Block Rockit to arrive. It is a 14+ machine with a ten foot grace frame. Since it comes with rear handles and a laser light I plan to give Pantographs a try. Where is a good place to purchase Pantographs? Videos to watch? Pitfalls and tips? I have access to a group buy from Checkers and Brewers. Please let me know if they have supplies I should consider purchasing.

Thanks so much!
