Cheaper isn't always better. Sometimes cheap silverware can have brittle necks that are hard to cork screw without breaking off, even if the neck itself isn't that wide. I got a bunch of forks from Dollar General the other day and broke probably over half of them trying to practice corkscrews.
Easy to bend is a good starting point, but if you can it's probably best to work up to stiffer forks for when you hand them to the spec. Lots of folks go for dominion, I've noticed, and Adam Strebler likes Winco forks. There's a product out for bending called Liquid forks, but don't let the name fool you...they're known for being on the hard side of medium as far as bending difficulty. Liquid forks also have no writing on the handle, which is kind of nice.
