Registry Cleaner and Internet payment security with Pay Pal question, can you help?

Hi, I am looking at registry cleaners to purchase and install on my computer. The two top recommendations I've seen from "Ask a Nerd.com are:

"XP Medic" (this scan found 119 errors and is made specifically for Windows XP and cost slightly more than the product below).

and

"Registry Patrol" (this products scan found 162 errors)

Can anyone tell me if they know anything about either product?

As well, I'm squeamish about purchasing online and would prefer not to, but I have been unable to locate either product through local vendors, but each site has an option of paying through Pay Pal.

Does anyone know of payment safety through the Pay Pal feature regarding online safety? I have never used this before, and wish to look thoroughly before I leap!

Any advice would be helpful, thanks!

Have a wonderful day, too!
