Theres still some decent deals to be found on K-horns and other models, but i agree 100%, prices are crazy the last few years and the "flippers" out there make it worse... just look at ebay for people "trying" to sell chorus1 for $2500 or forte1 for $1500 and alll other models are 2-3x what they should be selling for.
My room is similar sized, they had to be on the short wall and my seating position was back out of their sweet spot, bass was nice when it was right but seemed like every recording required EQ adjustments to sound balanced, and many simply sounded like crap on them, but sounded fine on all other speakers, just too darned picky and finicky for me. They looked awesome though in oiled walnut! I would have held on to them but had an offer for 2x what i paid 7 or 8 years ago, probably would have sold for $1000 more today.
My CF4 were satin black too, didnt mind it too much but the wood colored ones are nicer. I'm sure you know but the veneer under the black is the same real wood they used on other speakers, it's usually oak. Ive seen lots of satin black speakers be stripped and oiled or stained the veneer underneath, if its in good shape would be a lot easier than doing a reveneer.
Reviews are all over the place on V1,2, 3, some say the V1 is the best sounding but as you know dealers and customers didnt like them too much which is why they were changed 2 more times in their short run. In hindsight I think most of the bad reviews were because people werent used to the new different sound of the Epics vs other traditional klipsch models, today they are considered one of the best models klipsch ever made! All in all I know I liked my cf4s better than the K-horns in almost every category!
