Adrian,
OK... Take this with a grain of salt because I'm about to commit heresay here (hmmm, the spelling doesn't look right for that, but you get the idea). Is it really worth it to spend the money on an F1 or F2? Those machines are really small and you dump a fortune into them. By the time you figure out that you are never going to take a huge cut with them, I kind of wonder if you wouldn't be better off just buying a Sherline! You won't be taking a huge cut with them either, but their price is certainly attractive. Mind you, I *do* own a Deckel and I wouldn't ever want to part with it. And I'd love to own an F1, but I don't think I could ever justify the price for what you get. You can drop more for them, it seems like, than you can for a nice Deckel! And there is no comparison for the two (my opinion).
