I was at a point of extremes when I bought 5 AutoZone marine/deep cycle for a total of about $600 and 500Ahrs (~250Ahrs usable without damage). They are the standard maintenance free auto style which can be but are not intended to be watered. For me they were relatively cheap, readily available, easy to claim warranty, light enough to move/install/uninstall. They are also the easiest to charge and discharge since it is such a long standing standard.
There are certainly advantages to other technologies and disadvantages to wet cells but for now this solution has met my needs very comfortably. T-105 golf cart batteries would really be my only other concideration but availability, movability, and warranty claimability are hold backs. You also have to consider the charging system when choosing batteries. I have a 100amp balmer alternator with external charge controller and a ProMariner P Nautic 60-12 charger/maintainer. There are disadvantages to staying on shore power 24/7 but it is working for me right now. Maybe I'll change that practice in the future.
