Avalon Acoustics Ascent MKii value?


Hello

I found someone who is selling these Avalon Acoustics Acent MKii speakers.  Giant, grey/silver.  And I simply have no idea where to start in terms of making hi an offer that is fair to him and leaves room for me to easily sell them for a profit.  Any tips or any resources where I can find out more information about valuing these would be greatly appreciated!  Thanks!

If I'm not mistaken Avalon Acoustics did finish some early models with a durable flat grey finish. There may be issues replacing some of the early drivers. Using the serial numbers one could email them for any serviceability issues and their original finish.    

With maybe $2500.00 good  luck with resale that may never happen pass them up big time as they are history!!
Ascent Mk IIs are one of the classics. It's been years since I've heard these but I'm confident they still rank among the better speakers made.
Gray is the cheap crappy finish and it does not sound as good as the solid wood.
