$350 for the 2252 is a pretty good deal. I’d say the main differences here are the calibration and the analog vs digital scope argument. Analog may show you some stuff a digital won’t. They each have their fans.
I wouldn’t say the Tek is unfixable… especially in the PDX area, lots of Tek folks around still. The Rigol would probably be less fixable, although likely has some sort of warranty. How crucial is calibration to your planned use? -- Andrew M.C.

Mainly I’ll be using it to repair amateur radios, amplifiers, and maybe some debugging of digital circuits later. There is a guy on CL that is offering me an older Tektronix 2252 100Mhz analog scope with digital storage and integrated volt-meter for $350. He can’t vouch for its calibration. Alternatively, I’m looking at the Rigol DS1102E which is the same price. It is a Chinese made LCD based digital scope that is much smaller and portable and seems to have good reviews. It is 1GSa/sec, rated 100MHz with a million point storage. Which do you think is the better investment? I know that the Tek is a high quality device but it is over 20 years old and probably impossible to fix if something breaks in it. The Rigol is new but probably not well made but the portability and desk space I’d save seems like a real plus. I’m worried that it won’t be high enough resolution for doing the radio repairs but most IF frequencies in radios are around 465KHz so it might be fine. Or, maybe one of you guys has an older scope you want to sell?
