Re: Radarange...
try to find one that has had the power supply rebuilt, the capacitors in these will go bad with time. The plastic "roof" panel can be a problem area too.
We like and use daily the RRL-9TA series for it's combination of features such as the glass digital panel - easy to clean, program storage, Temp Probe, Touchmatic, and the more clean modern look, while some like the look of the heavy chrome door type, RR-9TA, both are otherwise the same. That said any Radarange is awesome, and there's lots of types to choose from...Craigslist is THE place to find one.
