Pc-oscilloscope or oscilloscope

[PIC2PIC]

I want to buy an oscilloscope. I saw these two products:

1.DSO-5200A 50GS/S PC USB digital storage oscilloscope.
Bandwidth for this oscilloscope is 200 MHz and is higher then bandwidth of the other one. Max. Sample rate is 250MS/s - i.e. lower then the other oscilloscope

2.RIGOL 1052E Digital Oscilloscope DS1052E 50MHz 2ch. Bandwidth is 50 MHz and is lower then the other oscilloscope, but Max. Sample rate is 1 GSa/s and is higher then sample rate of the other one

The price is about the same. What should I buy ?

I think that sample rate in single shot is the most important parameter. Sample rate in repetitive mode (50Gsample/s....) will never replace higher true sample rate. And 200MHz with only 250Ms/s will not give a readable signal.

Thank you for answering !
So you suggest me to buy no 2. Can you suggest any other oscilloscope about same price ?

I don't know the prices of these scopes. You can also try to buy an already used scope, like Tektronix TDS2000 family for exemple. I prefer a good one not new than a new one, good on paper, but poor in real life, like some low prices scopes frome China.
