Laser question

Panasonic DVD laser pickups

The 04 and up Panasonic silver colored VCR-DVD combos both shelf and
inside tvs had a problem with a cheap Laser pickup i ran into probably
40 of these over the years pretty much brand new still with a bad pickup

Over the years now servicing all sorts of DVD products i have noticed
this same laser pickup in even the cheapest units and now Philips . The
pickup usually has 2 yellow stickers on the back of it and they added
different types of white slide gears to them for different mechs
Anyone out there stocking these pickups cheap ?
