Small Second Monitor for "low cost"

I got this app a month or two ago and it works great! It essentially makes a second monitor for my MacBook Pro (which is extremely nice for an engineer in training) and it works good. The resolution is a little grainy with the settings I use. The resolution can be improved slightly with some adjustments in the settings but this makes my MacBook sound like a plane engine getting ready for take off so I tend to use low settings to reduce the possibility of my MacBook taking flight. Honestly, for a cheap second monitor, its definitely worth the $10.
