Monitor Calibration

It's still worth getting it.
Only the large "pro" shops know what they are doing. The average small little print shop on the corner never heard of color management or color profiles - they only know "save your jpg as a cmyk 300dpi"
There's always the exception to the rule however.

I was hoping the-cheap-one-will-do would be the answer. often not the case.
