I've never tried real British or Irish bangers, pork sausage with rusk and spices, so I've ordered a few from R. J. Balson & Son. I didn't order from their store in the UK though, they have a brother here in the states that makes and sells them online. I've also ordered some pork back bacon to see what that's like as well. My order will be shipped early next week and hopefully, all goes well and I like it. Hey, it's pork, what's not to like. 
Here's a shot of their storefront in Bridport. Established in 1515, it's the oldest family owned butcher shop in England. I found this image on Flickr and posted by Tim Russ.
