Toolmiser is correct, I would try to find when you can view the items in person prior to bidding and there's a contact number, they might be able to give you some more info than what you see on the page
Just beware there's a 19% that will be added on top of the price of winning bid with sellers premium and sales tax. Please account for this when you have a max price in mind that you want to pay. It adds up quick.
All the items you're interested is Three Phase power, except for the 12" Rockwell Disc Sander, it's 110v
The smaller Rockwell bandsaw and the belt sander is three phase, so unless you want to invest in time and money to install a VFD on them then I would pass on it unless of course you want a variable speed bandsaw which is super awesome to have but just beware of the $$ and time needed to make that happen. Also, swapping out the motor for a single phase version is not hard on these and a option.
They have some awesome machines for sale, but also be aware teenage kids have been playing with these for decades and they need to be checked out before bidding, it's not always cheap to repair, replace damaged or missing parts on these machines, it can also takes ages to even find a part that doesn't require you to pay crazy high prices for.
I think the best deal is the "(2) Work Benches w/ Vises & Tools", there could be lots of money in the small tooling and useful.
For me, I would be jumping on that Powermatic Grinder and putting a VFD on it, if it was selling for cheap. Would make for a great buffer and wheeling machine.
I wouldn't be surprised if the bidding gets more active on a lot of these machines based on how many bids there already are for the lumber in first listing. That is a lot of nice wood.
