Get along to the Stoneleigh convention on 18th April and you'll be able to buy what you need at discount prices for new kit (it's 2nd grade but likely to be better than 99% of 2nd hand equipment you might come across). I would guess you'll get a complete National hive with supers and frames for less than ?100, everything smelling of fresh cedar.
I lived in Low Town for 18 months. The little leaning black and white house in St. John St.
A few years ago I bought some poultry in Morville. They also had dozens of old WBC's empty in an area visible from the main road. I always meant to go back and check if they were any good and see if they wanted to sell. Worth a look perhaps?
