You may want to consider a DIGITAL scanner. I checked out the database on here for Tulsa, and currently it is a MIXED Motorola II system. Mixed meaning that some agencies are using analog voice, and some are using digital voice.
You can look at the database here:

Pay CLOSE ATTENTION to the field labelled MODE. If it says A=analog, E=encrypted, D=digital, and M=mixed analog/digital
Each one of those talkgroups are what I like to call a VIRTUAL CHANNEL. Each one represents a channel spot on the agency's radio. So you should be able to look at the list on the database and determin if the agencies you want to listen to are A, D, E, or M. If they're A then you're ok with just about anything that will scan trunked. Pro 97 OVER the PRO-95. I'll explain that in a second. But the Uniden BC246T would be a good selection too. If any of the groups you want to listen to say D or M then you MUST buy a digital scanner in order to hear them. If they say E, forget it... won't happen, EVER.
There is a thing called REBANDING, where the current public safety 800mhz frequencies are being shifted around, and this will require all radios that are using MOTOROLA to be reprogrammed in order for them to work under rebanding. The same applied to scanners. If your scanner hasn't been made to handle rebanding, or is not flashable to accept the rebanding change then your scanner will be useless for trunked systems which are motorola. The PRO-95 will not work with rebanded systems, so therefore it will be useless unless its EDACS or conventional. Plus its just a way older scanner, it lacks a lot of features that the PRO-97 and 96 have.
The PRO-97 and 96 either have already been modified to handle rebanding or there is a firmware update to fix it. Uniden's BC246T and BCD396T will handle it already out of box. If you can deal with ordering through the net or over the phone, I'd suggest getting a BC246 or GRE PSR-500. The PSR-500 is the replacement for the PRO-96. If you can't wait, then I guess radio shack is going to get your business. Don't expect them to be any help though. THEY'RE CLUELESS!
