All my exact thoughts, I also assumed it was going to go fast and all my other stuff was going to sit a while. I've owned 3 vintage Sunn heads and they weren't in style when I bought them. It was like I was buying trash, the people selling couldn't believe I even wanted them. It's up for sale here on TB, ILF, stonerrocklives, on CL and I posted it on my FB a bunch. Everyone is excited about it, but no one is buying. I could put it on ebay, but I only buy on there and I'm super nervous about weird stuff happening, like how Eyeball has had with people making claims because of buyer's remorse or something.
That's ok, that's most of the offers I'm getting from people I know online (and in person) "Oh man, if only I had money right now!". I don't take any offense or anything. The only thing aggravating me is the people trying to lowball and being really crappy about it, because they clearly just want to wait a while and flip it for over the price I'm already asking.
EDIT: Just took all my ads down and decided to hold onto it for now. I'd rather it just sit in storage and not get played than give it away for less than a reasonable price, just so someone can flip it. Maybe in a year, when the average price is higher, I'll just list it for the same price and it'll move fast.
