Samantha (apologies to all for doing this business here, but its faster!), maybe you can pick out two or three that complement the ones in Chris Timson's review (action? reeds?) and I'll include them. I think you can just send them to me through the Email here on the forum.
If anyone else has suggestions for things to include in new sections of the Buyer's Guide, let me know. I'm sure you'll have more ideas after I put the drafts up. In particular, I'd love to have some more photos of English system concertinas. We don't have any of the top-end models yet.
