I'm looking for 2 of the Grey Twin-Cannons for Powermaster Optimus Prime, along with the Hi-Q Powermaster unit. While I've found some on Ebay, I'm really looking for a fair shipping rate, not the $20+ shipping the people on Ebay want for such tiny parts. I do have Paypal, and would prefer to use that method for payment. Send a PM if you're offering to sell any of the parts. Thanks!
