Traded my TZ for a SM 2 years ago, 12 hour round trip in one day (Tampa to Mr Stack somewhere in South Georgia). Had my gf of the time riding shotgun with me. Made the drive because the SM looked in better shape and SMs were fetching about 1K more than TZ then from what I saw. About halfway home on the return trip I got a sinking feeling in my stomach and started missing TZ.
Fast forward to now and I finally got both SM and TZ back in much better shape than the first ones I had. TZ is my all time favorite pin, never letting go of it again.
