I'm interested in getting the powersharp setup and was wondering if anyone owns one? Does it work pretty good? Worth the money? and do i have to get a different bar to use it? and for anyone who doesn't know it's a low profile chain that comes with a sharpener that you just slide on the end of the bar and push the saw against something and run the chain for about 3 seconds and it sharpens your chain. I've never done a self chain sharpening that was anywhere near as good as a new chain and figured i'd see how people like this setup before i spend the big bucks for it. So, thanks for any info. and here's a link to their site http://www.powersharp.com/
