I got my SP-1 back today. I tested it and the new board seems to be a good upgrade, well worth the shipping charges. Only problem is that it took SmartParts a week and a half to install the board and get the gun back to me. And I only live 45 minutes away from their factory. Their definitely not in a hurry to install these, so be warned if you plan on having the gun for a game the week after you ship it out.
