I find that using AA batteries is the best option. Costs me 2 bucks for a hockey game to get 8fps...I use either one load or two loads of AAs that i buy in bulk from Costco. That's what I think is the best way to get 8FPS because you don;t have to get a charger or anything and you can buy replacements anywhere.
It does seem that way. But assuming you use them pretty frequently, then over time, it's not just the most expensive way, it also generates by far the greatest amount of toxic waste (even assuming that you dispose of them properly, which 98% of people don't). Here's the math:
16 Energizer 2650mAH rechargeables (two loads for your grip) will cost you about $45-$48 (we'll say $48 to be conservative). You need a really good charger to get the most benefit from the rechargeable batteries, not the crap 15-minute chargers they give you; so add another $90 for a MAHA 8-cell charger with individual circuits. That's $138 as an initial investment. I'll even throw in $0.50 per week for electricity to recharge them, although that's probably grossly overstated. Initial investment $138, weekly recurring cost $0.50. If a 20-pack of Duracells goes for $6 at Costco, then your initial investment to start is really zero and you're consuming $4.80 in AA batteries every week.
Not too complicated once you've got this far. The rechargeables save you $4.30 every week, so you'll break even on your initial investment in just 30 weeks. After a year, the alkalines have cost you $250 (actually $249.60, but don't nitpick me) and the rechargeables are barely at $164.
Your initial $138 investment has generated $86 in profit during the first year: a 62% return on investment. Where I come from, that's pretty damn good. And every year after that, the rechargeables cost you $26 per year in electricity while the alkalines cost you $250. Save $224 per year, get a return on investment of 162%.
Rechargeable NiMH batteries should last 600-700 cycles, but let's say 500 which is about 10 years. Total savings: over $2,100. And at the end you get to recycle 16 batteries, instead of eight thousand, three hundred and twenty (8,320) alkalines. Even assuming you dispose of them properly, that's economically suicidal and environmentally disastrous. And of course, 98% of people just throw them away and put poison in their landfills.
I'm sorry... I fail to see any valid points in your "cheapest and best" reasoning for alkalines.
Wow, what a smackdown! Nicely laid out arguments Rodolfo 
Anyway, I think if you have other camera bodies that use the EN-EL4/4a, then that's the best route to go.
