One DSE601 burned atty, second one on best path to burn (at the moment just bunning the taste).
DSE601 has no spatre or removable atty, pipe by itself is "atty", mean you have to change pipe body to get new atty.
I didn't try Jazz Pipe, but looks very solid with exch. atty (510 or other).
I think Jazz is good choice, by the way DSE601 atty (body) cost cca 30$ plus transport and other costs.
So, if you sumarize costs including spare atty's you will reach Jazz price faster than expect.
