Check out some of your other local $.99 Cent stores, or "Nothing Over A Dollar Stores".
I started out with Dollar Tree colanders, then found a huge "Nothing Over a Dollar Store" nearby, that was less than Dollar Tree (which really isn't a dollar, huh?). I also started buying the kitty litter pans to use as drip trays for my seedlings. Far sturdier than anything else I've used. Can hold a loaded tray in each hand and no collapsing.
Scout around your area for those little shops, and stop on in!
