AR ES 1 our buy a newer TY

Depends on how much you want to spend, IMO. The price you've stated for the ES-1 (unless it comes with an arm) is higher than the selling price when it was new. I bought mine in the late 1980s for $500. Over the years I fully tricked out my ES-1 with just about every mod available from Merrill and Scillia. The mods did raise the performance of the table.

At that price you should get something new. There are plenty to choose from!

Too high a price for a stock ES-1!

I just checked EBay. Found 3 for sale. Prices range from $1K to $1.25K to (get this!) $6.8K!!! And the $1K was a "beater" in poor condition! The $6.8K one did have a Magnepan Unitrac arm, plus 4 cartridges (Shure V15 MR, two Pickering's and an AT 404). Apparently these are some VERY optimistic sellers!

I'd rather spend cash on a vintage Technics 1200 - and I did! A much better, right-out-of-the-box TT! Too much tweaking required for the ES-1!
