If the Tek/Sony 300 series counts as "miniature", I'ld like to add the 314 10MHz analog storage scope. Due to the fragile storage tube, its getting harder and harder to find (or assemble) a unit in full working order. When in good shape, they produce a really crisp and detailed picture despite the low acceleration voltage of 2kV total. The storage mode unfortunately comes along with reduced contrast since the flood guns slightly illuminate the whole screen. Nevertheless, I'm quite happy I've been able to save such a cute little piece of history from the dumpster and extend its "life" by a few decades...
