For what it's worth, I just took the plunge and ordered a Felder KF700S saw/shaper.
Among other specifications, the machine has a 3.2M (10') slider and runs on single phase power.
I spent a long time researching stationary saws, and like some of the above commenters I came to the conclusion that the SawStop with sliding table was definitely not for me. I've been processing a fair amount of 6/4 White Oak recently, and have grown weary of the limitations of handheld machinery in terms of straight-line ripping and processing of solid woods, and am finally ready to invest in a stationary saw. There is a cooperative shop nearby in Minneapolis where nearly every member has their own slider, everything from a pair of KF700 saws with 6' sliders, all the way up to an old Panhans with a 10' slider. There's a early (I think prototype) SawStop in the shop, apparently it's rarely used...
There's a lot to like about sliders, but the safety aspect is what really sold me. It's a different way of working compared to a traditional North American cabinet saw, but since I've been working with my Erika for the last several years I've been pretty well insulated from habits related to traditional cabinet saws. Opinions vary, but in theory just about any operation can be performed on a slider of sufficient length, in other words you may never really need the trip fence if you didn't want to use it that way.
It's just a different way of working and thinking.
I was originally looking at the Hammer machines (I also have a A3-41 and HS-950), but it really wasn't a huge jump to get into the Felder line, and they have multiple machine lines so it's pretty easy to get a machine that matches your budget. The Hammer K3 line looks nice, and if you get a shorter slider there are still ways to straight-line rip longer boards using a sled that indexes in the slider t-slot. Just remember that the Hammer and Felder accessories don't overlap, so if you think you'll really be using the machine a lot (even as a hobby) it's worth considering if you can stomach a smaller K500 or K700....
Something to consider is accessories. The Grizzly, Maksiwa, Laguna, and other machines are frequently going to come with a few more bells and whistles as compared with a comparably priced Hammer, but the Hammer will have a greater variety of accessories, which will allow you "grow" into your machine as your wants/needs change, whereas accessories for the other machines may need to be home-brewed. Either is fine, it just depends on what you're skilled at and how you enjoy spending your time.
