Sorry if this offends anyone, but I would stay away from what I term "consumer" machines.
I recommend these 3 features: an induction motor, cast iron trunnions, trunnions mounted directly to tabletop, not the frame.
If you'll look closely most of these machines are direct drive motors (translation low hp), in reality just a little better than a circular saw. You will also see some with stamped steel trunnions and minimal, lightweight cast iron in the top.
The fence systems have come a long way, even the cheapest saws have fairly decent fences, but IMO you just can't beat a Beismeyer.
This said, depending on what you're doing, your budget and your personal philosophy regarding tools, one of these saws may be all you need.
