Used DA polishers - what to look for?

I hope so. For that price, I'd buy a third as a spare.

Speaking of used polishers, I picked up a like new used 21 Mark II on eBay today for $272.

I’ve noticed quite a few 21s up for sale. I’m still using the original version with no problems. I use my 15MkII on vertical panels, the 21 works great on horizontal ones.
