Complete and working is usually $200 to $300. Minty is $500 to $600+. Parts sets are $20 to $100. Look inside for alignment tools and the metal covers over the tuning assembly. Both are rare and unobtainable. A working meter is a HUGE plus as there's no easy substitute. Sets that were set up as part of a diversity system usually had no meter. The large main tuning knob is hard to find, even broken ones are desirable. An AR88 face had engraved lettering and is easy to restore/refinish. A CR91 needs to be silkscreened. Good luck. Leaky oil filled capacitors are possibly PCB contaminated but the jury is out on that one. The voltage selector on the back panel is usually broken from someone resting or dropping the radio on it's back, breaking the selector. All tubes are common. Proper alignment is a pain to perform. These are tough sets. Most I've encountered dead were easy to get going.
