They're only TRAYS, for cryin' out loud...

Get on Craig's list and go scrounging.
Get whatever you can find.
Cheap.
Lot's of 'em these days
Get a mongrel mix in any size you'll need now & in the future.
Some will work better for specific tasks than others, but you'll find that out as you go...

Darkroom life is more than Designer Brand trays.

Sheesh.

The whole bloody point of asking for opinions is to learn from the experience of others, so as to not needlessly flush $$ down the drain; something like 'measure twice and cut once'. Sheesh indeed.
