Depending on your pace, this could be a lifetime plan in six steps.
Step 1) Talk the guy into knocking 65-70% off his asking price.*
Step 2) Buy a functional cash set of minty RHC Paulsons.*
Step 3) Play with them until you want a change, or your stakes increase to the point that you need a snapper.*
Step 4) Spend dozens of hours painstakingly removing the Starburst cancellation.*

Step 6) List set in the classifieds, ultimately end up selling them by the barrel.
