There are different degrees of dead, too. Do you get any assist at all? Does it start using the noisy backup starter, or do you not hear a starter when you turn the key (indicating it's using the IMA)?

If it's not too far gone, you can possibly resurrect it and get a few months to a few years out of it by buying/building a grid charger. I assembled one for myself for ~$30.

When you do get a new battery, I'd suggest grid charging it 2-4x per year to keep the cells in balance (don't do it more frequently as you can lower its life expectancy by frequently overcharging), and avoiding baking it.

Can you give me a parts list for the 30 dollar grid charger?
