I wanted to get a DS4024E with 200MHz BW but now the DS7014 seems just so attractive.
Sadly I could only afford that scope with 100MHz BW and now I am struggling really hard.

The fastest Signal I would be going to measure would be a 50MHz Clock signal - do you guys think it is worth it to still go for the DS4024E
for the higher BW or should I get a DS7014 with 100MHz BW?

I hope I asked this question at the right place...sorry if I did not.

For a 50MHz clock signal you'll need at least 200MHz to see some harmonics an have a clue about what the square wave looks like. 250 to 300MHz is even better. Still when spending this kind of money it is wise to look at other brands or even used.

That is true but I thought about maybe renting (or borrowing) a scope with such a BW just for this one signal in the worst case or ( the case that I hope for) -
Maybe the DS7k series will also have some hardware hacks to push up the BW limit.
If not so then maybe I can afford a Software BW upgrade some time in the future...
The new ASIC (not to mention the touchscreen) is just so tempting :/

If you really want a nice touch screen and ASICs then buy an R&S RTB2000 or RTM3000 series. At least these scopes work and have 10 bit ADCs. AFAIK this is Rigol's first ASIC based scope and it may have some issues. I wouldn't want to be an early adopter for new technology which can't be fixed by a software update.

You definitely have a strong point in that regard!
But I do not really need the 10 bit resolution and when it comes to the rest then the Rigol - at least on paper as far as I can see- is the clear winner when it comes to price and performance or am I missing out on something important that I can't see?

Yes. There are many pieces of test equipment which look great on paper but don't work in real life. I really see what you mean and I went down the same rabbit hole already. A couple of years ago I spend over 2000 euro on a newly introduced oscilloscope which didn't work and I was foolish enough to believe the manufacturer (in this case Siglent) would fix the firmware soon. I ended up throwing it in the trash (=money wasted) and bought a different oscilloscope because I needed an oscilloscope which works. Again: read the posting from Karel. His experience is very similar to mine. If you want a piece of equipment which works then stay clear from Rigol and Siglent. They don't test their firmware at all. Sure the A brands slip up too but A) too a far lesser extend and B) they make things right even if it means taking the hardware back and fixing it.

You forgot to add C) charge you 2-3 times what "B" brands do for the same (or less) features content.
You get what you pay for.
