I went from a Jet 6" to a Griz 8". Both long beds. The Jet impressed me with the fit and finish. You can find the Jet used for $300 or so. The 8" jointers go for $400 and up. Delta DJ-20s for up to a grand, used.
I finally sold the Griz when I restored a 1930s Wallace short bed.
I won't go back to a 6" as a lot of stock is wider than that.
