newbie wanting to know about loop peddals

[Tyler <programmer651@comcast.net>]

Hello! Since I just joined Looper's Delight a few months ago (and the 
publications's been 
going for over 15 years), I call myself a newbie. Now, I basically 
understand loop peddals; when 
your foot is on the peddal, it will loop a sound that was put into it. 
Some people, for multilayer purposes, 
use multiple loop-peddals. The newbie part of it is, how much does a 
loop-peddal cost? Where 
can you get a loop-peddal? How do you set one up? Any special settings?
