Hey, Super, interested in making one of those for me? (let me know)
To the OP. When I started I got a knock off Oregon grinder, but I found that my hand filed chains cut faster. But in the past week I got me a Silvey 510. I was not happy with the knock off for alot of reasons, and I looked at some of the Oregon's (forgot the numbers, 511a's?) and was still not impressed. I just filed my first time tonight with my Silvey and am VERY happy with it. I have yet to cut with it, but from looking at the chain It is way better than the Oregon knock off.
