For less than $200, you are kind of stuck with these type of scopes...
JYE DSO138mini / DSO-150 / WAVE2 :: very low-end, ok for audio, better than nothing
Owon VDS1022I :: USB scope
FNIRSI 1014D :: desktop scope
There are many other cheap scopes too, but they aren't as great as the next group.
If you can push your limit up to $350 to $425 region, then you can choose from these desktop scopes...
In general, as the price goes up, so does the features and capabilities too. There are more model#'s in my list.
