New ones are, but I got my Tektronix 2430A for free (with all opts) because someone was getting rid of it. Usually you can grab one for around 300. More importantly, it can still be calibrated, traced to NIST, it has a higher bandwidth, and I know that my probes are all going to be up to spec without capacitance problems. On the other hand, it's a lot bigger than this device, but I'd say it's probably just as reliable (and probably still more serviceable). No Math/FFT stuff though. tl;dr: I'd get this for convenience or as a second device, but I wouldn't really trust it.
