Hey Pauly: You should call or email Lloyd Peppard of MAD for info on the kits. I have the Ultra 4A which doesn't come in the kit form. A good friend recenty built the Triplex and it pretty much looked like the one on the website with a few changes of his own. He loves the triplex and that's the direction I would take if I was doing it all over again as you get the choice of the different circuits. I still have my Foreplay and it has a special place in my heart, but I think you would be happier with any of the Mapletree products for the long haul. Also, my friend that built the Triplex also had previously built a Foreplay. I am certain he would tell you the same as I am. In addition, he thought the Triplex was easier to build as there was more room to move around when soldering all those joints. The Foreplay box is still a little cramped for the ole soldering gun. Good luck with whatever you choose. Let us know how things turn out.
