Hey Mike.
A vertical leg press is a great compliment to a home gym if you have
the space to include one. You are hard-pressed (no pun intended) to
find one in commercial gyms any more. They started going extinct in
the late '80's--probably a combination of safety liability and the
fact that they are more challenging than the 45 degree horizontal leg
press (I love guys that brag about being able to leg press 1000
pounds, but can't squat their own body weight!).
I've always liked vertical leg presses and have one in my home gym.
They are good for leg presses, but I really love to use a vertical leg
press for calf raises. The squeeze and burn you can put on your
calves is worth every penny to owning one.
The model you provided a link for looks pretty good, but the angle
that it puts your neck in is not favorable. It will definitely put
undo stress on your neck, which should be neutral and more parallel to
the weight rack. It does not look like it, but if the neck pad is
adjustable, you could correct this issue.
I found another model on eBay that appears to offer better ergonomics:

A couple of things to be aware of with vertical leg presses:
1. I suggest covering the pin holes that you are not using on the
upright slider shafts. The hand grips (if provided) are not always
optimally placed make it way too easy to inadvertently have a finger
or skin from your hand pressed into these holes. Can you say
"guillotine'?
2. When not in use, always have the leg press in its lowest position
with pins out. Otherwise, you are asking for trouble (especially if
there is weight on the rack and you have small children running about
the house!)
3. You may need to lubricate the weight rack shafts with white grease
or silicon spray. My vertical leg press was not very smooth until I
performed this step.
