Just been to Springwood Meats in Braintree, Very reasonable prices and top draw supplier, Anything needs he can supply, He is a meat smoker himself just starting out. Had a good chat with him (Rick) and pointed him to this forum for advice as his smoker has paint peeling on the first smoke! was not cheap thing, offset smoker. Hope he comes sees what is going on here and the support available.
