If you can find one, go for a Ferrograph RTS1. It is an all-in-one
audio measuring set, includes distortion and level, has a low
distortion oscillator and can measure drift and wow and flutter. They
were made in the UK, so you won't have to pay shipping charges.
Measures down to 0.1% full-scale, so if the distortion is below what
you can measure, you don't need to worry about it.

Yes I've got one of they. Make me an offer I can't refuse;-)).....

You'd be surprised what they go for on Ebay. Especially if in good
cosmetic condition as most are rather battered. And with the optional
balancing/monitoring unit.

BTW, I've scanned and OCR'd the instruction manuals for both units as most
are supplied secondhand without. The circuit diagrams are best photocopied
to double size. I've cleaned up both the circuit diagrams but not the
other parts and exploded views which were all pretty poor on my originals.
