As Tomic stated above, they use very expensive components and don't worry about the cabinet in the 2 and 3's. If you set them up properly they crush most of the competition that can cost twice the price of each. Not everyone gets them as they don't smear and are time and phase correct as folks have said. They are as true a point source in a conventional speaker as you will probably hear. Feel free to PM any Vandersteen owner on here as we will probably tell you teh same things. Older ones are usually sold as folks move up, like I did.
Since the 2's are the best selling high end speaker of all time and have been on the market since 78 I believe, there will be many for sale. Most are in great shape if taken care of, but if someone can afford the 2700, the newest ones are SOOOOOOOO much better as they have trickle down drivers and components from the original Treo's ;)....Yes, they are that good to most ears. JMHO
