HI! i Have for sale a Optotronics RPL 450 green laser... I had it for about a month. I maybe used it enough to take its battery down about half life (tops about a half hour of use) It is perfect. when i ordered from Jack (Optotronics) i have both end caps and 2 batteries...And everything it came with case,charger, spec sheet...The reason I am selling it is that we just had a newborn and im selling all of my toys! I could post pics but it is brand new and comes with everything on the website as described... I paid $1,300 and I would sell it for $800... You can contact me at 570-332-5646 or E-Mail me at JNRBONK@YAHOO.COM for info. Thanks Rick
