OSLS dichros are *excellent*. i bought a set a couple of months ago and am very happy with them. their blue dichro works great with 445.
it is important to note they have two qualities. the cheap ones they sell on ebay (85% reflective) and the more expensive (99% reflective ones). i'm using the high quality set.
when i upgraded from laserwave dichros my waste beams disappeared...

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
