Which Battleship?

A very quiet couple of days for me, seasonal workload and commitments plus being away last weekend meant that I haven't had much time online again. I did catch a couple of kills, a Catalyst who foolishly shot at me while I was trying to get a Thorax at a gate to shoot me (the Thorax warped off)and an Amarr Shuttle that was sat on a Faction Warfare complex gate for some odd reason, yeah a SHUTTLE! Go me . . . ;)

I have been thinking lately that I should train up a Battleship for nuking things like POS's, not for roaming piracy. We're talking pretty basic fit for the time being. What I would be interested to hear is which Tier 1, non-faction Battleship gives the best sustained DPS. I'm not fussed if it's not Minmatar. If you have a recomendation of a fit to match your suggestion of ship then that would be super!

After my comment about being very poor in the isk stakes I stumbled into a faction rat cruiser yesterday that dropped me a Faction medium armor repairer & a Low Grade Snake implant. Once sold, these two will go a long way towards that Battleship, so I look forward to hearing your comments.

PS, everyone have a nice Christmas if I don't post again beforehand
