If it was "only" 10-15 grand, they would probably sell a lot more units, but the latest and greatest Waterlase MD sells for $69,000. Of course, you can lease it for $11-1200 per month for 5 years. Some dentists swear they make back the lease cost in the first 3 or 4 days of the month, then the rest of the month is gravy. I have read that the $69000 is cheaper than other medical type lasers, but have not verified this.
