Although I'm not an "experienced Central Florida scanner" I feel I can weigh in:
Let's have a look at the database shall we? If by "limited access" you're referring to encryption, I'm not seeing any encryption on your county's system linked below so that's good news. If talkgroups were encrypted here they'd be listed as mode "DE" rather than "D". So my advice to you is check the database for the counties you want to scan. Fully encrypted talkgroups have an uppercase "E" suffix (as in "DE", "TE" "P25E" for conventional, etc) Partially-encrypted would have a lowercase "e" (De, Te, etc). Hope this helps

With that said if you're looking for a scanner recommendation, go with a Uniden SDS100 or SDS200 as you'll likely experience
