After the hassles I've had in the past with finding the correct clock rates for my pixels, I've been thinking maybe an getting an Oscilloscope would come in handy for verifying signal actual integrity.
At the moment I know flickering at low brightness means the clock is too slow; and high brightness flicking means it's too fast. But getting the sweet spot has been a bit of guess work + trial & error. This has me thinking that maybe with the assistance of a scope I'll be able to get a faster idea of the correct clock by visually seeing how the data waveform is.
Am I correct in assuming this?
If so, what scope should I get? I am deciding between these two...

- Rigol DS1052E @ $329 (then firmware hacked to 100Mhz) - https://secure1.bluecentral.com/emona/shop/scripts/prodView.asp?idproduct=72Or
- Rigol DS-2072 @ $839 - https://secure1.bluecentral.com/emona/shop/scripts/prodView.asp?idproduct=2816
- or am I going to need something insanely more expensive? Or a proper logic analyser?
