If your handy with the saw Dan, you can make your own collminator, because anything under the 100 dollar mark you will have to collminate it anyhow. The only difference between making your own and buying one for 100 bucks is the size and the money.
I built my own collminator (search the threds for Laser Collminator and find the one that has me as the author) and it works a treat all up costed me about $16. The only thing that i have done to it since then is put a piece of foil over the opening for the laser beam as to make it a tight dot as the china specials don't always have a nice neat dot.!
If you have any other problems just pm me and ill help you on that one
