Well I took the plunge and bought a Laserworld 250mW greeny off eBay and it arrived today from Germany incredibly quickly via UPS.
Total cost including shipping was £159 (around $80). It has a 'buy now' price of £189 but the seller will haggle (make an offer). It seems very well built in a decent heat sink and while I haven't a meter I have no doubt it is chucking out the full 250mW. It burns black tape at several feet.
The dot can be seen in sunlight at 300 feet. Can't wait for tonight to see it's full capability. Beam seems nice and tight. Downside it is only TTL but I understand that Laserworld can modify units for analogue and for my purposes TTL is fine.
I wondered if it was working when I first switched it on as the slow start takes around 2 seconds to come up. It set me thinking of the idea of adding some more capacitance on my die4drive drivers to make the slow start the same and hopefully prolong the diodes life in my reddys.
