We have Target brand polycarbonate glasses in our RV. They are hand washed, much newer, and used less frequently so they are crystal clear.

The WS glasses were expensive compared to the Target. I can't say if the Target will hold up under the dishwasher like the WS. Anyone out there have Target polycarbonates that have experienced dishwasher abuse?

The cracking in the dishwasher was the major drawback with the non-polycarbonate versions we had previously used.
The preservedproducts I mentioned have been through the dishwasher twice with no ill effects, but we simply don't use them that much.

They aren't Target brand. Apparently (after a bit more research) I can get them at Crate and Barrel (clearly not a cheap store) or any of a number of natural foods stores (including Whole Foods and Sprouts).

Not sure how they'd hold up long term, but on the other hand they are cheap and easily recycled, so you could toss them if they started getting icky after a year or so.
