I love my basic.
I am not remotely sad with it.
I would love the pass-through slot. I can’t say I would use it often; but when I want it, I want it.
Example: My brother has a replica sword signed by the swordsmith that designed it for the movies, and he showed it to me again this week. He would love to etch that sharpie-made signature into the blade. Whether that would add or diminish the value, he wants that. Long things… I would love to do.
The tiny notch up in power would be nice. Cutting through 1/4 inch baltic birch instead of cutting through most of the 1/4" stock. Maybe I just need to refine my settings.
The notch up in cooling would be peace of mind… though I haven’t had cooling problems even on 100+ degree days. (38+ for the base-10 scientific world)
I am very happy with my basic. If I were discussing a second machine, it would be a pro… mostly for the pass-through. I figure, if we’re discussing NOW vs. zen-like patience, I’d want the upgrade. Give me a reason to give it up.
Also, If I were back in line, I see the pro line moving faster than the basic.
