The GFCI breakers are about $100 each where the receptacles are $20 each. My understanding is that you only need one GFCI receptacle per breaker to protect the whole breaker, but check with an electrician!

Good thing I am an Electrician!

GFCI breakers range from about $90 and up, the plug is around 15-20 depending on the style.

So yes it depends on how you wire the GFCI plugs. They have a Line side and a Load side.

Generally speaking you would come from the panel and into the Line side on the GFCI plug. If you have more plugs down the line you can just put the next circuit into the LOAD side of the plug and everything after that would be GFCI protected. (Basically anything wired directly off the GFCI plug down the line is GFCI protected, and anything before the GFCI is NOT protected. Thats if its all wired correctly)

When you buy a GFCI plug it has an instruction sheet on how to wire it and also clearly marks on the plug which side is which. Most have a yellow sticker over the Load side so you don't end up hooking it up wrong.

If you needed some help with it I am free on weekends and some evenings to help as well.
