The Seydel Blues Favorite is a nice little diatonic. It has an aluminum comb and a metal body, including stainless steel covers. The reed plates are made of German silver, and it has standard brass reeds. It is ergonomically designed to be comfortable to hold, as well as to play, but the shape and construction is second to the quality. Made in Germany, it is a solid, dependable mouth harp. Serious musicians will appreciate the fact that it is available in 29 different keys as well. So, you can purchase one to experiment with, or you can round out your collection with several in the keys that you need.
