Thoughts/experience with used Thiel speakers


I had owned Thiel 1.2, 1.5 and 6 in the past.  I am now in the market for a smaller set for a 2nd system.  I believe Thiel is out of business.  My question is:  what can a person do with a set of used Thiels if they need a replacement driver or other service?  Thanks
