Very few if any true 12V deep cycle batteries. You don't want a combo battery or a marine battery as they are not true deep cycle. They might be able to discharge and recover a few times, but not many. A true deep cycle battery has a better chance of recovery; although you should not completely discharge them. The cheapest way to go for true deep cycle is a pair of golf cart batteries (most are 220AH). Two 6V batteries take up more room than a single 12V, require maintenance (add distilled water); but are not expensive, easily found, and work well.
Mine are 5 years old Interstate golf cart batteries. Always maintained them (almost, got a little low on water a few times) keep them charged (put 200W of solar on the roof a few years ago). Specific Gravity readings are still good in all cells.
If the ability to add water was a real pain in the arse, I'd think about AGM.
