Just to clarify, adjusting the parallelogram design is not hard IMO but it's extremely tedious, as in having to move it a very small amount, check all sides, move small amount, check all sides, rinse, repeat. Though I suppose that applies to any jointer adjustment, but working with the cams which are easily exposed rather than having to shim is much more pleasant to me. If my fence wasn't warped I'd love this jointer for what it is, good enough. With my fence being warped it's just ok but like I said in my previous post, I make due and it really hasn't affected me that much thus far but I'm also just a hobbyist.
And yes, soon as you step up to 8" you'll need 220v.
