Agon is now a retail outlet.

However, one can select "All Equipment" to filter out music.

Thanks for letting me know about that!  I never noticed that button!  It still would be nice if you could filter out any categories you want.

I haven't had a ton of purchases here, but all went through pretty smoothly. I always request to talk with the seller by phone before purchase and if I get the "do not trust" signal I don't buy. There are lots of forums and blogs out there without a commercial or financial aspect to them. Maybe try there?

I have been around her since near day one (at some ancient point I needed to reregister, ...  Anyway, never a problem.            
When I see an ad asking several times what an item is worth? I LAUGH. Who cares... Do you think you are the gon 'value police' ?Some ads claim a 27 year old item is only 8 years old. Some double or triple the original MSRP. Some ask crazy money for gear. Not my problem.    
Latest I laughed at was a Threshold FET 10 line stage preamp asking $1800+ and the Audio Research Sp-10 asking $5,000(I bought a ARC Sp-10 mk2 for $600  cash and a few broken bits of junk worth $200, about nine years ago. IMO tht was all it was worth, but I sold it here for $2,300 anyway when it was selling for 3K LOL.)        
(I recently bought a FET 10 line AND phono for $900)      
I look at it as folks unable to deal with reality. Who cares. Anyone can ask any price. Anyone is free to say nope. Works good.

Believe it or not this is not personal, it is a warning to the people out there who are being fooled by the obvious marketing of items that are overpriced, not an attack on you, personally. I am unfollowing this thread, my message is out there and I don't need this misandrist attitude.
