Two questions:
1) What do we think of the Rigol vs Owon o-scope, say 5022S? Apart from 25 vs 50mhz.
If you look into an alternative to Rigol then have a look at GW Instek oscilloscopes for quality.
I recently purchased a GW Instek GDS-1152A scope after spending quite a lot of time looking at the various options available to me. On the whole I'm happy. Plus points:
+ The 150Mhz version isn't that much more than the 60Mhz version (the 100Mhz Rigol is a lot more than the 50Mhz one)
+ I wanted as deep a memory as possible (2MPoint, compared to the Rigol with 1MPoint)
+ Better build quality than the Rigol (inside and out)
+ Brighter, better display than the Rigol
+ Lifetime warranty
+ Could buy from a reliable bricks and mortar retailer without paying a premium.
+ Seems much more stable and less buggy than Rigol
Minus points:
- Costs more
- No push button knobs or light up buttons
- Less triggering options (no slope, no alternate trigger, no rise and fall)
- Zooming on signal interface isn't as nice (this is actually quite a big thing)
- Writing to the SD memory card takes ages with full 2Mpoint memory depth
- PC software is awful, really really bad (but the command set is full and works well)
