i am going to start out with a 996xt I think. Figure out what my county plans to do with encryption. I don't want to spend $500+ and it become a paperweight. I do like the grab and go factor of the 436 and every where I go it's phase 2 currently. My county is going phase 1. I do REALLY like the 536 though. If by income tax time, if wifi is there I'll just pick that up instead of the 436 instantly. Maybe it will be cheaper too. Bearcat warehouse has it for $589 currently.
