Square Taper crankset

[mtbiker87]

Need a square taper crankset for a project I'm working on. Cheaper the better. Not looking for anything special,don't need to be perfect, just serviceable. Mountain preferred, but road would work. Arm length around 170mm, give or take 5mm either way. Not picky on BCD either.

I have a set of Shimano Deore LX cranks if you want them free for the taking. It is a 3x set but for some reason the middle chain ring is missing.
