Hey,
First and foremost, I'm not a projector guru. I'll do my best to get you any information you need in order to evaluate this laser - but you may have to bare with me in that this really isn't my area of expertise. Also, I have very little reputation to my name here on PL. I have a moderate amount on LPF, for whatever that may be worth.
The background on this laser was described here:

I got incredibly lucky with this purchase, and somehow managed to purchase this for $182 on eBay. I feel like I stole it. As awkward as it feels to say this, I wouldn't sell it for that little. I enjoy this laser quite a bit, and I think it's worth more than the $182 I paid for it. So for $182, I'd keep it. But, if it's worth more than that, I'd certainly like to free up the cash to use for something else. The cheapest 473nm I could find from China on eBay was $888. Again, I'm not pretending to know what this is worth, but I would imagine that somewhere between what I paid (about $220 all said and done) and $888 is reasonable.
This laser is very stable. I just ran a 20 minute LPM test, and here is a graph. It peaks at 372mW, but then very quickly comes down to a rock solid stable 215 to 225mW, where my guess is it would stay for continuous usage. I ran the LPM for 20 minutes, thinking this was a good time frame. If you guys need me to run it longer, I'm happy to.
Here are the details from the previous owner:
- 2mm beam diameter at aperture, with very low divergence.
- Originally paid $1,850.00 plus shipping in January of 2010, and has 40-50 hours (* plus my own ~2 hours including today's LPM test) on it.
- Originally came with a one year, 10,000 hour warranty.
- Very simple operation. Plug it in, and add 3-5 Volt dc to the analog wires coming out of the power supply.
So again, I'm happy to try and figure out anything that is important to a potential purchaser. The condition is good. The PSU has some cosmetic wear on it. I also built a simple DIY analog trigger so that I could power it up (basically, a 4V power source with an on/off and momentary button on it, inside a black hobby box). I'll include that.
