I just bought the em0480. The only advice I can give you is stop reading :), it will do you head in. I bought this one because it was the best I could afford/justify. Just about everyday I come on here and I think I should have gone the rocky but even 2nd hand it is double the price I paid. Yeah I might regret it down the track but it is better than the preground I was buying.
If you enjoy the shots you are making then that is a good thing, no matter what machine grinder you have :)
