For comparison, I have a Harris 3-9" LW BiPod...
Cons:
*The ModPod does not have spring loaded legs.
*The lock on the legs have three set position locks.
*The legs require two hands to manipulate. This is not a speedy bipod.
Pros:
*VERY lightweight
*The side mount leaves your bottom rail open, or in my case leaves room for my hand.
*Open and closed position is tight, no rattle.
*The side mount also creates a different fulcrum which allows a different element to stabilizing your rifle.
I have yet to actually fire a rifle with the ModPod installed. I have this installed on my .308 (still no barrel). There is another option out there, if you can find it. CAA made a side mounted bipod for a while. I think it was discontinued. I'm not a big CAA fan, and eventually gave up on them. I'm pretty sure theirs only came in black. As for the $150 price tag, I think I got them on sale somewhere or my Brownells discount. I really dont remember. You can usually find them on forums for between $100-$150 depending on the time/location.
