I have had good experiences with clark tk22 in my PzIII and Panther. I'd go with clark personally. It's not that difficult to set up. I'm pretty much an electronics noob myself and got it running pretty easily. (with the help of the internet)
I bought a T55 many years ago with the electronics included. I keep reading about how they suck, but i'll probably try them anyway since I have them already. If they really do suck, then i'll probably go with the clark board myself... if I ever actually build the thing
