I would suggest contacting an Estate Dealer or two, although it's not a full Estate, it's enough value. They have the contacts to price everything and find buyers. Yes, they will take their cut, but you know, think of the trouble and effort to price, post, package and get paid for all of that equipment. And the LP's? Sell one or even a few at a time or try and sell and ship that much in one sale safely? And if even if one sale goes south or something doesn't sell, you'll end up with less money then just paying their commission. My two cents, I am not am Estate Dealer.
