I opted for the Special 20s. They seemed to be high student / low professional and I've been very happy with them. I got almost a full set of major keys which seem to cover most of the songs that come up at the local sing-alongs. They have not disappointed me. I was keeping an eye on some of the web based stores and one of them ran a really good sale on the Special 20's. GC matched their price, so I got them right away at a discounted price.
In the future if I need to replace one of them I may opt for one of the higher end harps to see if it makes a difference.
