I use a Picoscope as well. Very happy with it although as mentioned you do need bench space for a laptop as well. On the other hand, that means a bigger screen, capability to store traces, etc. Horses for courses...
In my case, this replaced a Tektronix dual-trace 'scope, complete with delayed trigger timebase, etc. That had some hardware issues that I needed a 'scope to diagnose, hence the new one. Overall, similar spec for a fraction of the price - amazing what modern electronics can do for peanuts.
That's not easy to answer...Quote:

If you just want to test logic and simple, low frequency things then you can use basically anything. Beware that many of the small and cheap battery operated ones don't have any mains protection and have limited maximum values, so if you intend to use it around a CNC then you should be careful what you chose. Also beware, that the cheap ones may not have good enough display update frequency and may have VERY limited buffer. Many things to consider. The higher the sampling frequency per channel the better it is, but they also cost more.

... which have better trigger menu. Apparently, the Hantek can be upgraded to 200MHz, but you do this at your own risk if you decide to buy the Hantek.

Go and have a search/read over the EEVBlog forum. Lots of reviews/posts/comments about various scopes.
Personally I have a PoScope, which I've had for years, and it does the job when I need it.
Having to use a laptop isn't ideal, although I did recently use it with my 8" tablet which was better.
If it was something I used more often, I would probably invest in a DSO, however the PoScope is handy in that it all sits in a small box with all it's leads, tucked on a shelf. Even a DSO would probably take up much more room.
Have a look at the reviews on here. He was keen on the Rigols and chipping them a few years ago.

I did not read the above post before i posted but another plug for eevblog.
Thanks for all the input, Really does seem to be horses for courses. I was leaning towards a cheaper bench scope to learn on but I have been offered a cheap second hand scope and PSU's from a workshop clearance.
trouble is they wont confirm it works but said it does power up, except the screen is blank. I haven't got the full details at the moment but should the screen light up even with no input? I'm assuming there should be a back light?
If I go and see it is there a quick test to check, never used one before so sorry it that's obvious.
"Powers up, blank screen" covers a whole multitude of possibilities.
If it's a digital scope then I'd expect something on the screen. Even if the trigger is set and untriggered there would generally be some configuration/setting data displayed. If not digital, at the cost of scopes these days I wouldn't entertain an analogue scope.
If it's a CRT (rather than LCD/TFT) then it could be as simple as the brightness turned down, but that's rather a bit too hopeful I think.
I'd tread carefully. How much cost and effort are you looking to risk on this (i.e. "free, around the corner from you" is a bit easier to swallow than "200 quid and 200 miles round trip"). If you want a second pair of eyes (I've rejected driving from Lancashire to Devon, btw), and can share details then feel free to PM without any motive on my part other than to offer help.
An additional advantage of the new cheap scopes is the don't take up much room, Spend some time on the EEVBLOG.
The ones in the videos above are tiny compared to the old ones. certainly a big plusQuote:
