Yeah. Not sure what happened to XM15. He started out offering the pump kits at an awesome price and then just got behind or what. He hasnt really been active much from what I can tell. Last project I sent to him he ended up cancelling and sending my money back. Rainman seems to be your best bet ATM. Luke has hinted at a pump kit, but he has so many projects ahead of it, that who knows when that will come about.
