Used CS 3500, worth to buy or not?

[JJC]

Hey guys, I am looking for a scanner that can scan full arch impressions for clear aligners. As you guys know that deep cavities and undercuts in the impressions are difficult to scan so I am thinking of getting an intraoral scanner.

I saw several used carestream CS3500 for pretty cheap prices.
Is it worth a buy? It will be used mainly for clear aligners fabrication.
What’s the difference between cs3500 and cs3600?
Does the cs3500 have the option of locking one part of the scan and merging with a second impression scan?

What do you guys think?

get the 3600 the 3500 was good at the time but is way out of date now, the other option is the medit i500 which is a great scanner.

Did you end up getting the 3500?
