The Hohner Special 20 is an excellent harmonica and is fairly inexpensive. Most stores will have them priced between $20-25, which is great for how high of quality this harp is. The sound quality is excellent. This is my favorite harmonica to use; I've owned four Special 20s in different keys and find that my playing is better on these than on any other harp I've tried.
The only problem I have found with the Hohner Special 20 is that sometimes the break-in period takes a bit longer than usual for a harmonica. This has only happened on one of the harps I owned so it could have been user error.
I highly recommend this harmonica to anyone that is interested in getting into harmonica playing, or anyone that is currently playing and is looking for a new, quality harp.
