Mr. Bunny may have a cottage industry making and selling kits. He's also the developer. If you want to buy a kit, he's the best person to buy one from. And he's got a link to his paypal account on his homepage. (Listed in the user box above.)
Files and Parts
Generic/Daughter_part and CarrotStraightener. (As a gentle style recommendation, it's good to try to keep all your parts and files on the RepRap wiki rather than scattered around so that Mr. Bunny doesn't have to use a scripts and so on to get stuff back onto the wiki.)
