I cannot recommend Owon. Their DS7102V had serious noise problem due to bad power supply design. The problem is well documented, but the Owon didn't consider that to be fixed under warranty leaving the oscilloscope badly crippled (read: unusable) when measuring small signal levels**. Otherwise the oscilloscope is good.
** Quote from their response: "Sorry, the problem not belong to our warranty, and we only can reduce noise now, but can not have not noise." If I had understood it correctly, they did fix the power supplies in later revisions reducing the noise considerably, but it was not considered something that is covered by the warranty for the earlier revisions although the warranty period was still valid.
