Cgs synth

i am new to analog modules. i have a few synthesizers.com modules that i won on ebay. i want to start building my own. i was hoping some one out there could help me on where i can get some module kits that would be compatible with the synth.com mods. i am also new to electronics. so i need something with very good instructions. my wife tells me im just slightly more intelligent than a monkey. so maybe some kits that monkeys can do. i need a VCO kit, envelope generator kit, filter kit(LP, BP, HP),LFO kit and amp kit. i have looked at the MFOS.com page. the thing is i don't know how good they are. any assistance will be greatly appreciated. thanks, Trevor
