Homebrew PCBs

Hi,
I'm new to the idea of homebrew PCBs and was wondering if someone could offer some assistance on what thickness is easiest for working with for copper-clad boards.

There is a fellow on eBay who sells various types of copper-clad.

First of all, he sells FR-4 (clad on both sides) in .030, .047, .052, .060 thicknesses.

Then, he sells CEM (clad on one side) in .033, .047, and .060 thicknesses.

I understand that the thinner it is the easier it is to "break" into smaller pieces.

I also understand that the single-sided boards might be more suited to ground plane construction.

Any other tips? 

Thanks!
