Thanks everyone for the suggestions.
So I did seek and actually found (Studioratlollipop thanks for suggestion) a store with new unopened X3 Live for under $300. Before I pull the trigger and purchase a new X3 Live (even if is discontinued) instead of getting the HD500X , , my last question to the forum:
Note I play for a wedding band, top 40 music, some rock, etc. I also new to the playing live scene, really inexperienced, the question is:
If $ was NOT an issue, and you owned an X3 Live that is broken beyond repair, would you buy another X3 Live again instead of an HD500X at this stage of the Line6 Technological evolution? Experts, would you do this?
