I'm with you man. Why pay for something you won't use. Why not just measure the dimensions of your rear surf lockers? The dimensions they give you should be pretty accurate. Don't forget to reinforce the walls. I wish I had a pic of my setup. I bought the U-channel steel wall shelving track. Used them as support struts, fastened to the divider wall with stainless steel nuts, bolts and washers .I installed 3 per side and never had a problem. I bought the black U-channel tracks from home depot.

WM sells a aluminum strut set for reinforcing divider panel also:

A little more expensive, 80$/side but looks nicer.
The U-channel tracks I found, provided more than sufficient support. I never saw any bowing of the wall.
Also, save yourself some grief and if you go with the 1150's go ahead an order 500lb lead at the outset, so you're set to go at vacation time. :)
