I'm not really blaming my tools here, I know I need more experience. But, is it easier to grind straight lines etc. with a higher quality grinder? My homemade grinder does a good job but I don't know if some of the problems I hAve grinding could ve helped with a more "true" machine. I guess I'm getting a little frustrated. I will keep at it because I can't afford a kMG right now but did any of you see a difference when you switched to a higher grade machine?
