Now that I have multiple Macs in the house, I was looking for a simple, cheap method for Remote Desktop. Apples solution is a bit expensive for my blood, and then I heard of SpyMe on a podcast. Can't remember which, may have been MacBreak Weekly.
It is very simple to install on each Mac and provides an excellent solution at a fraction of the price. Only $15 for 3 computers. If you have multiple Macs, you have to try this.
