Hi Bob,
Good news that you finally have it!!!
Maybe you have done this GB too fast, so not all interested LPF members were at that time online (happily I was, however it can happen that I am working on a project for months without coming online) or did not have enough time to estimate the amout of sets necessary for future projects.
I am making design of an upgraded version of stiropyro gun and correct 16 beams from TWO! NUBM44 blocks and such a DIY would take 8 sets (each for 2 beams), so I already want more than 7 sets I have ordered at this GB!!!!!!!!!!
