There are several scope suppliers from China, Rigol being one. They're
probably accurate and reliable enough and I believe Wes Hayward, W7ZOI uses
one in his design work. At the recommendation of Jeff, AC0C, I purchased a
Hantek DSO5102B. These scopes all have a similar look and feel. I wouldn't
be surprised if the Tek DSO was made by Rigol under contract.
Recently, Rigol has introduced a line of very inexpensive RF spectrum
analyzers that offer very good res. bandwidth performance. These are
portable analyzers with hi-res SVGA screens. If the specs can be believed,
they appear to be at least on-par with HP from about a decade ago. Screens
are multi-color with 10 divisions (100dB) of on-screen dynamic range.
