I have a 120mW green module in a nice KD50 host, actual graphed average output is 118mW, lights matches, pops ballons, etc very quickly, uses a single CR2 photo-lithium battery (easy to find anywhere batteries are sold as in Wal-Mart, Menards, Home Depot, etc) - shipped with case in the USA for $125 (the module alone is $110 through O-like) - The laser is in "as new" condition and includes power graph, instructions, etc - It's a little over your budget, I realize, but it's a really nice, stable laser and would be a great start to your "mid-powered" collection. PM me if interested and I can send pix, etc. (ships same day payment is recieved from US)
