You should look into Unison as well, including the Steve Goodson Unison which is a custom build, really rare and hard to find these days. In my opinion, the standard models of Unison work really well compared to Selmer's. If you are looking at a budget of $1,000 - $2,000ish, i'd recommend getting a stock unison.. but if you are in the neighborhood for $3,000 to $4,000, i'd definatly go with the upper echelon's of the Selmer's such as the Mark VI.
