most retailers dont even let you haggle from the sticker price of 24kUSD, which in Canadian means you arent getting one for less than 30. whether or not you have cam and computer is irrelevant.
whoever told you no more than 10, was trying to lie to you to flip it.
however, your phrase "I would just hate to realize that I asked to little for it." seems suspect.
if you are selling this machine at only 52 hours then one of three things has happened.
1. you don't actually like the produced quality - however at 52 hours its hard to say how much you actually know to begin with. at 20 minutes a unit, youve cut a total of 156 units.
2. your lab is bankrupt and assets are being sold. this might explain why you dont know its value. but if you did buy it you could have the receipt and quote from your retailer.
3. it is stolen, in which case anyone interested might like to see that serial number, and pay by cash.
we know you work at modern dental works in Sudbury Ontario, and from your profile its doubtful theres more than just you working this place. surely you would know how much you paid?
the fact you ask in USD price is suspect, given you are at least a 3 year old lab in Sudbury at this point.
your Facebook page has a picture of the mill, dated jan 21 2015. in 1 year and 3 months youve only used it 52 hours total ?
yes i am acutely aware i have dug up way more info than i should have. but i had to be sure. this post is super duper creepy, and i know it, and im not sorry.
