Re: Getting Started...
A cost effective alternative that I played around with for a while is to go out to lowes and buy a 4\" angle grinder (Typically around $40 for a cheap one) Look for one that offers variable speed if you can find one. I have been able to cram 4\" cotton wheels on it, but haven\'t had any luck with fitting a sisal wheel on. The thing turns at about 10,000 RPM so you can get pretty agressive with it.
