You raised a good point - non-digital.
Without knowing the model number or flash code, assuming it's "non-digital" would not be a good idea.
If it's an XTS or newer radio, it's digital capable. Wether or not it has the digital function turned on would depend on the flashcode.
There's a lot of older XTS series radios dumped on e-Bay that may support P25. The XTS-3000's usually are dirt cheap, but you can find good deals on XTS-2500's and 5000's if you keep your eyes open.
I will confirm that with the seller. He says the radios were just retired from their EMS. I think the county is selling these. What do you think?
Look closely at the condition. Some public safety radios do NOT lead an easy life.
If it comes with a battery, assume it's bad and be ready to order a new one.
Same with the antenna, antennas take a lot of abuse.
Find out what the flashcode is, and make sure it has the features you want before buying it.

There are no amateur radio frequency allocations in the bands these 7/800MHz radios cover. There is no "FRS", "GMRS" or "MURS" like frequencies in 700/800MHz. Receive only is all you can legally do with these radios unless you work for an agency/business that has a license and they are willing to let you add your own radio to their system.
Your scanner is much more flexible.
The audio on these Motorola radios can be much better than what your scanner will do.
You'll need the correct programming software and cable. Not hard to get, not expensive.
Software has a steep learning curve. But there's lots of help on this site.
If it's a mobile, they are not always as simple as "plug it into the cigarette lighter". If you are looking at remote head, make sure all the parts are there.
