I've got the same scanner and couldn't do without it. I listen to mostly local HAM, so the P25 units were overkill for what I wanted. I also want to keep up with VHF, FRS, GMRS, CB for local intel.
Are the P25 units nice, no doubt, but besides being a lot more dough, they're 10 times harder to program.
I've also got a BC355N for base scanning, but the BC125AT goes everywhere with me, mostly commuting around town.
