How much should I pay for a 2001 Thiel CS 3.6?

Hi guys
So - wanted to share with you, for closure - that I bought the Thiels with a set of Goentz cables for $1400. Thanks everyone for your insights and help!!
I'm very happy. Guess now I need to open a new thread on best amp for these speakers under $1000... currently thinking about NAD 356 BEE w/ DAC although it may be low on power to drive these babies..
Cheers

Hi guys
Thanks A LOT for the helpful info. My situation is that I was planning a modest setup -to spend up to $1500 on speakers and pair them with a NAD 356BEE amp (e.g. was considering B&W). All of a sudden came across this unique opportunity with the 10-year-old Thiels which are obviously orders of magnitude better on paper but (1) I'm concerned I may not have the expertise to verify they are in good shape (2) I'm concerned about having a very non-matched setup where they will not sound good with a $800 80w-per-channel amp.. Cant afford more now.. But may b golden opportunity.. Any thoughts are welcome I'm such a novice in audiophile world.. Cheers and thanks again

Thanks everyone
I am so confused..
Came across a chance to buy these speakers around $1300 but really didn't plan on buying a high power amp until I met these speakers. there seems to be a consensus that these speakers must be driven by very strong components.
If you had this money for speakers and a 80-100W amp as a given, would it make sense to buy these at all? in this configuration, could they actually sound WORSE than a new pair of B&W you could buy at the store??
Thanks

Hi everyone,
Thanks for all the detailed advice!! you guys are great.
So I decided to do something that most audiophiles will probably consider a sin...
I'm going to take a commercial Sony 125W amp I have lying around and will go to the seller and hook it up the Thiels tomorrow to listen to how they perform with a low-grade amp If they sound good I'll get them and with time will look into upgrading upstream components gradually and making them sound GREAT.. I'll keep you posted, thanks for all the help
