Check out Battery Sharks for the Sigmastek (sp?). 1 battery 2-pack. If you exercise the single battery without shipping option, you can get 4 for $115ish shipped (at least to my zip code).

I don't expect a rule change on this, but buying cheaper 12V batteries should be on all teams' radar for practice and non-competition use. Proper battery management will get at least 4 seasons of use.

There is no real difference between the batteries in capacity or construction. When I was on 836, we ran several brands (MK, Genesys, National, Sigma/Battery Sharks) and they were pretty much identical in all regards using an accepted test procedure for batteries. adciv can probably provide more detail if you require it.
