You can always buy a Complete Module then simply order the Host seperately,
if by high power your just looking for something that produces a green beam when its dark you can always take your chances ordering some of the cheap Aussie stock from ebay that say "1mw Green..." usually about 8 bucks and shipping is pretty fast(2-3 days sydney to melbourne), downside is the quality, lack of IR filter and you may be getting a 5mW laser or a 50mW laser (part of the fun for some i guess) either way i've picked up a few of these and my "1mW" laser is pretty frickin bright and burns with very little focus, on the other hand my other "1mW" laser is pretty piss weak.
