so far i've got 5 reds(thanx SenKat) and 2 Blurays(thanx DDL) so i've built a few. The only reason i'm thinking about it is because the company linked earlier in the thread sells the crystal stack already setup and glued for $69 so that right there solves half the problem for me. I didn't want to mess with 2-3 different crystals trying to align them.
Sorry for the thread hi-jack but I will be making my own post in the green section soon, just getting base ideas here since we got rolling.
