I'm preparing to embark on a rather ambitious scratch-building project that requires MANY similarly-sized styrene bits and the ol' Exacto knife and ruler just won't cut it (no pun intended). So... I'm looking into "The Chopper's", but which one? The way I see it: The original "Chopper" has a nice size hardboard/masonite base with an aluminum guide fence and razor blade "chopper". "The Chopper II" is more money but is made of cast aluminum with a rubber mat cutting surface, but the work surface looks smaller than the original's. Let's take cost out of the equation. I don't mind spending a little more money on a quality tool, as long it is the right tool for the job. Also, I work in N scale so the difference in work surface size shouldn't matter... or does it? Any opinions? Anyone prefer one over the other? Is "the latest and greatest" better?
