Just did a little math. Here's a few examples:

PA500, 21 lbs, $1500
PX120, 25 lbs, $500
----------------------
46 lbs, $2000

PA500, 21 lbs, $1500
PX320, 26 lbs, $700
---------------------
47 lbs, $2200

PSR-S900, 25 lbs, $1700
PX120, 25 lbs, $500
------------------------
50 lbs, $2200

PSR-S900, 25 lbs, $1700
PX320, 26 lbs, $700
------------------------
51 lbs, $2400
