I said UP TO, lol. I suppose "cheap" may be the term in dispute though, <$50 is cheap for 5mW.
LaserLands were selling their 100mW NewWish on ebay as 5mW for a long time. I didn't see any up recently when I checked a few weeks ago. I spoke with one of their CSR's at one point about their eBay auctions and why the pricing was different (cheaper) and they said the ones they mark as 5mW that are high powered ones are the less reliable units, and the ones on their site were the more hardy/stable ones. Add grain of salt, they were probably trying to sell me on the website price, heh, but you never know. Wish I would have saved the emails but that was before I re-registered here on LPF. Back then I was looking for my "getting back in to the hobby" laser.
