honestly, if i thought you were sincerely trying to offer help i probably wouldn't have questioned it.even so,anyone who has any dealings with me will find that i am more than trustworthy.so any serious potential buyer who has any questions may pm for more personal request/info.besides,now that i see yob is only making 20 more,if this don't sell i don't mind keeping it..don't get me wrong,it is still for sale,i just don't mind keeping it(it is a good powerful laser)..sorry for any misunderstanding
