It's an OK price. It is a good drill press, 15" delta. It has the delta light which alone brings $100. That drill press with variable speed is rather rare. I have the same 15" model, but it is the step pulley model and mine has the large production table. That one has the standard wood working table.
The MT2 extension you see there is actually an accessory (rare accessory ~$50) that screws onto the spindle. If you plan on putting large MT2 bits in there and drilling, don't. It is just not that rigid. You will need to get a JT33-34C which is a chuck with a threaded collar or a MT2 to JT33 adapter and a chuck. Either way you are looking at needing a chuck. (~$50)
The rotary table is a bit random. I have never used a rotary table on a drill press. On the mill, yes, but not on a drill press. I supposed it could be done, but I am not sure if that little table would like the weight of the rotab. Then again, it is hard to tell the size of the rotary table from the pics.
If you like the press, go for it. If it was me I would look for a larger (17" Old delta or clausing) before I spend $500 on that. JMHO
Things to check when purchasing...
=Bearing noises. For $500 is should be really good (no noise). However every older machine I have bought has needed a few bearings.
=Spindle runout. Those MT2 Extensions act as a lever arm for the tiny spindle on little bump allows the spindle to be really tweaked.
For the money I would much rather have this...

I also have a 17" just like that, mine is older with the cast iron belt guard, but other than that same drill press.
The 17" is SO much heavier and more robust. Plus that one comes with a chuck. It is a dedicated metal working model. The spindle on the 17" is a full MT2 solid, so you can chuck up MT2 bits and not worry about it.
Or this, it is the non VS version of your first press
