I used the 260 and its almost identical brother the 260NS (higher impedance, and more expensive) for many years. That, and a Tektronix 454 scope, were all I needed as a design engineer nearly all of the time.
I now own a Tek 475A, better in all ways than the 454, and much faster, and a Tek multimeter; but I wish I had a 260 too.
The autoranging in my nice modern Tek TX3 multimeter, though, has saved me from some missteps that might have fried a 260. Even in the TX3, I once blew a very expensive fuse by trying to measure the voltage of a car battery while set to measure current. That certainly would have destroyed a 260; in the Tek it only blew a $30 fuse.
Getting old has made me stupid.
Edit: I just looked on eBay and there are many 260s listed at reasonable prices, but no 260NSs.
Additional edit: I've confused the Simpson 260 and the Triplett 630. It's the 630 that has the more-expensive brother, 630NS. Old age really has made me stupid.
