Default For Sale ~ DIY 220mW Red ~ For Sale

Would anyone be interested in my SenKat diode based DIY 220mW red laser? With fresh alkaline batteries it will pop balloons, melt dark plastics and light matches. IEC class IIIB.

Duty cycle of 30 sec on, 60 sec off. Simply because it's mounted in plastic. The casing is plastic except for the battery sheath.
Takes 2x AA Alkaline. Lithiums will work but not recommended because it has only a basic driver, and they may overdrive it.
Power measured at ~270mW drain with a multimeter which (via an approximate formula) works out to ~220mW optical output.
Case is 22 cm long from protective tailcap (covers push on/push off button) to aperture.
Focussed at exactly 15 cm from aperture but this is adjustable with a pair of pliers.
Oh, and most of it is covered in duck tape. As I say to people, it may be covered in duck tape, but it's still a high powered laser!

Disappointed in having to sell this but I need the money now, and still have one LD left. :'(
Asking maybe 150 US, negotiable. If noone buys here I will sell it on ebay for around $200 AUD.
If you're worried about the power I can send it via Greg (SenKat) so he can test it, however you'll have to pay the extra.
What you think guys?

If you havn't had the output tested, is the 220mw a guesstimate?
