Maybe the Owon or Hantek $100 ish dollar ones?
The Hantek DSO2C10 (up to DSO2D15) is a far better scope than the 1013D, but is also has its problems, like all these cheaper ones. I have no experience with Owon scopes. You better ask this question in a new thread with a bit more information on what it is you need to measure. Like specific voltage levels, at which frequencies, etc. Maybe mention specific models you are looking at, to get the user experience from others here on the forum.
The 1013D and 1014D of FNIRSI, YAPOOK, etc. are both bottom of the barrel performance and hardware wise, so only for the very low end user they may have some value.
I bought one because it looked nice and the specs are not bad, until you find out that they are false. Not 100MHz bandwidth but ~30MHz. Not 1GSa/s but 200MSa/s. Only 4KB sample memory per channel which is not even fully used. Lots of bugs in the original firmware. The 1014D was gifted to me.
Had fun reverse engineering them and got my moneys worth from that, but have not used them for real measurements.
Did use the Hantek DSO2D10 I own though, and it works ok. For the more sophisticated stuff I own a couple of better scopes.
