Include the Siglent SDS1102CML too. The Rigol 1000z series is probably a touch above. The Siglent can be had for about $356 US. (just checked on Amazon) Look at some video reviews too, so you see the screen resolutions and differences. I have the Siglent and have not put it through any heavy duty use, but it seems to work quite well for what I've done with it. I have a Rigol DS2072A and it's a significantly nicer 'scope, but then, it's twice the price of the Siglent.
