Now is the time to sell, holy crap the money people are paying is obscene. If you had a 5-7 year old machine you bought 2-4 years ago you can probably sell for double what you paid.
Coworker of mine sold his 2012 in the spring for what he thought was crazy money, 4500, he said he can't find anything as good or better for less than 6 right now. Zero supply, crazy demand, the loans are so cheap. That was a 3000-3500$ sled back in 2018, sheesh.
I've already got 2 sleds and one butt so as long as I don't blow anything up, I'm good for now. Come late Feb there will always be a few deals.
