Polk County, WI P-25

I am not sure where to post this so here goes, what scanner should I purchase to scan the new P-25 system I live in Polk County, WI and counties around me are Burnett to the North, Barron to the East, St Croix to the South and to the West is Chisago County, MN. I have two old scanners one is a Bearcat, Radioshack, today while reading the news paper an article caught my eye, Burnett County has been ordered by the FCC to switch by August first of 2014 but a glitch has come up with the local Indians over the right to access one of the antennas. I believe Polk is right behind. Will the new scanners be able to catch both conversations dispatch and car?

Thanks

Jim
