Please forgive if my question sounds silly but will all great minds here this must be the only reliable place to get a true answer.
I bought and have been using M-20 for about two years. I hear M-25 is out and as any dumb user i ask myself if I should upgrade ? My M-20 is rev. 5E (7.25.04J6)
Since I have no idea what versions exist I would like some opinions on if an upgrade for me to M-25 is something I need? Should I buy just new heads from Leon? I live in KS and mostly I see Kustom laser guns around here.
