Andrew - my toms are outside in large pots on a south facing terrace. I water in the evening when they're just beginning to lose turgidity - probably about twice a week at the moment - when I pot them I leave quite a big gap at the top of the pot (about 4 or 5 inches) and when watering I just fill that up with the watering can.
This year I'm growng only Heirloom varieties - I've had BER on two fruits on which were on the same truss of a plant which I understand is prone to a little BER - otherwise nothing else - so far!!!
Last year I was battling with Late Blight - by nipping out every affected leaflet twice a day and quarantining affected plants I managed somehow to contain it and we still got a crop off all plants (Marmandes) in what was a really horrible year.
Good luck with yours
