I was just looking at the site and at Wanderers review. They look and sound great, and seem pretty fairly priced. I think they're moving up my wish list. I'm particularly interested in the A, so if anyone has one, I'd be interested in what you think about it.
Obviously, I thought the SZBE was a pretty cool whistle. I don't remember who ended up getting it in the last round of horse trading, but at least one other person has had it now and hopefully will chime in with their impressions.
I am now the happy owner of the SZBE that Greg reviewed. It has a reedy tone, not unlike that of an aluminium Syn. It is loud and very precisely made. It's a great deal for the price- around $75 if I remember correctly.
I have a brass high D and really like it a lot. I wrote a review about a month ago on the board, so if you search, you should be able find it. The review has pics and a sound clip.
