Same as my s/n here. I sell from time to time but generally I just put up BINs with Best Offer. The problem is most people won't hit anything even when it's reasonably priced so at this point, I send most stuff to Probstein or PWCC to auction and deal with it. I get better percentages with them than selling on my own a lot of the time, plus as you know, they usually get higher prices.
I know you hate them but I'll list a positive for consigning through each.
Probstein: Generally really quick payouts. I'm talking within a couple days for the most part. They get your cards, put them up quickly and pay quickly, plus they deal with the hassles of returns (which is gonna be much less likely on graded cards through them or PWCC), etc.
PWCC: You can send them stuff to pay for auction winnings. There's only been a handful of times I've spent thousands out of pocket on a card but I've done it numerous times through their auctions and sent them cards to cover the cost. Besides some shilling shenanigans, I think that's the reason their auctions usually end the highest.
If base LeBrons are $1,300, which is the most ridiculous shyt I've ever seen with cards, a base Kawhi RC should be like $5K and Silvers should be $10K.
If the current auction for the Silver Curry goes over $2K, I'm selling mine.
