You may wish to investigate Broadcastify Calls. I listen to it quite often to keep up with Minneapolis happenings.
If you still want to get a scanner, the only one(s) you'll be happy with are the Uniden SDS 100 (Portable) or SDS 200 (Mobile).
"Things" in Minnesota are digital, trunked and quite often simulcast. The SDS models, which are costly, are the only ones the gave consistent satisfactory results. Also, the Minnesota system, particularly in the Twin Cities/Metro Area are very complex and not for the faint of heart to program and monitor.
There is some movement toward encryption so you may not hear everything you want. Again the Broadcastify Calls will have good lists of talkgroups in your area that are still "in the clear".
