This post led me off on a bit of a hunt as I wanted another couple of kits to build (having just done the Paranormal from TGM). De Gier does stock the kits and the PCB's. However I also found
http://www.tonepad.com/ who provide a selection of PCB's, diagrams, etc. I've ordered 5 of them and sourced all the various components from my own collection, Maplins, RS Components and Smallbear Electronics in the US. A couple of unusual value caps I got from
http://www.justradios.com/ though had to buy more than I needed to make a minimum order.
Once I have everything and some working pedals I will report back with more details and prices, but the whole lot is costing around £85 so far though I still have 3 boxes, 10 jack sockets, 4 switches and a multitude of knobs to buy. Still seems like exceptionally good value to me if you're handy with a soldering iron and can read a circuit.
Oh, the ones I'm trying out are clones of the Tubescreamer (with correct JRC4558D chip), CE2 Chorus, Brian May Treble Booster, Tremulus Lune and Green Ringer.
Small tip on printing out decals. If you have a scanner, put the box with holes drilled face down and scan it (cover with a towel to stop too much light. You then have a JPG of actual you can open in a graphics editing program, add your lettering, etc, then print out actual size.
