Does anyone have the inside dimensions on the 120Qt or 150Qt Igloo coolers? I'd like to fashion an incubator and I am trying to choose between the two models. The 150Qt is over twice the expense with very little more horizontal space. Is this extra space worth the expense? In other words, will it allow for more Iris (etc) shoe boxes...or just more unusuable empty space?

Thanks In Advance,
Chris

PS -- This is for BP incubation.
