I am trying to decide between getting a machine with the ZS1450 ("rated 110, max 120") and ZS1250 ("rated 90, max 100"). I would like a bit more cutting power, but I engrave a lot of detail into wood. Annyone have an idea just how much difference there is in the detail abilities? (I would pass on my 80w to my daughter's business, so this wil be my only machine.)
