There’s a lot of ambiguity in that phrase.

I think for some sellers advertising “recently shopped” means that they took the glass off and wiped what they could reach with some paper towels and 409. Usually there’s some left over pieces of paper towel that tore off and the ‘mechanic’ didn’t notice or was too lazy to remove.

“Needs a shop” probably means at very least that 1) it’s dirty, and 2) rubbers need replaced. It also likely means that coil sleeves need replaced and/or some coils, switches, bulbs, etc aren’t working 100%.

My last “needs shopped” BSD purchase required a new mist board (or repair), a couple of switches, new rubbers, and good cleaning.

Never hurts to ask for seller to clarify what they did or what needs done.
