I would choose the Powermatic first. The price is a bit high in my opinion, but is a respected name. I just don't like the wings more than anything. Next would be the deltas, however if something happens, getting parts may be an issue. I personally wouldn't touch the craftsman or the last one.
if you are in a position to save some money, the Rigid from Home Depot is a good saw. Other people don't like grizzly, but their hybrid saw is a good saw to start with. I believe it is around $750, looks like a cabinet saw, but the motor will be closely related to the Rigid.
I have a Porter Cable saw and I didn't like the fence, so I upgraded to a vega fence. Looking back with the price of the saw and the fence would have been almost the cost of the grizzly. I should have saved for a cabinet saw, so I never need to upgrade.
So to wrap up this long response, ask yourself the following question:
1) do you think this is something you will stick with long term?
If the answer is yes, at a minimum, buy the grizzly or save for a PM1000 or the 1.75 hp SawStop.
The punches are designed to create a mortise for pegs not through holes. I do quite a bit of this. I did a how-to on this but, it really shows nothing more than Darrell or Marc's how-to's. I use a bradpoint bit to locate he position, slip the punch over it, take out the bit and tap the punch to fix the position. I then use a twist bit to excavate, smack the punch, excavate, smack the punch and excavate. This gets me to my usual depth of 1/4" or so with things coming out nice and clean. You can see the smacker I use in the link. Prior to that I used a regular hammer but, I started mushrooming my punches so I switched to the hefty but, wood faced hammer.
