I would stick to legitimate test equipment manufacturers, which
needn't be that expensive as many are available very cheaply at
hamfests today. The exception would be a serious oscilloscope-"simple
scopes" can be had for five to twenty dollars all day and repaired by
jackleg methods, but modern, calibrated, DC-coupled triggered sweep
scopes with attenuators and calibrated sweep are probably best bought
_new_. Or late model(still supported) refurb from legitimate test
houses (i.e. not *ucker.)

Fifteen years ago one was safe in saying "buy nothing but a Tek scope"
but Tek does not build actual oscilloscopes, per se, today. Iwatsu in
Japan is one of the last respoectable builders of scopes. Hameg in
Germany may still be at it as well, but I don't know.

People who "can't afford test equipment" are usually full of ****. And
if they really aren't they need to get a job, or a better one at any
rate. As the True Hams said in the old days,"If you have time to ham,
you have time to build". (There are very, very few true hams left.)
