Greetings! Long time radio nerd, first time poster. An XTS5K M3 has been on my radio bucket list for a long time and I recently started looking in the various corners of the internet for one. I'm learning as much as I can about flashcodes and software versions and whatnot, but I'm having a hard time determining what the differences are between a $500/600ish radio and an $1100/1200ish radio. I get that FPP adds value. Any advice would be appreciated! Thanks in advance!
