Hi Dan,
I'm down in the Cotswolds near Cirencester and just joined the forum - it would be great to hear how your cheesemaking is going, I'm early days in this adventure. If you're still looking for equipment I'd suggest googling catering equipment auctions, there's one near me and they have bain maries, massive stock pots, small fridges etc. There are also some great commercial cheese operations up your way (wensleydales for e.g.), I'm hoping to get up for a visit.
