I'm on the lookout for a portable scope too and I'm sold on the Hantek 8060, mainly because of the built in function gen. 60Mhz scope at 250Ms/s (new ones) and 25Mhz generator. It can even record a wave on the scope, save it (up to 15 ! ), and then play it back on the wave gen. They both work simultaneously, actually the probe compensation signal comes from the generator, it doesn't have a separate 1kHz square out. Bonus is a 1%
DMM that's isolated from the scope, so you can use them simultaneously.
I have sourced one locally for the equivalent of 600$ and I'll probably have it soon.
