Either oscilloscope that you mention earlier will be good. I use a 200 MHz Hantek.
A couple notes on oscilloscopes,
Speed, 100 MHz scope is good but if you can afford a 200 MHz, or faster, go for it.
memory, memory allows you to capture events over a long period of time. The more memory you have, the longer the time you can record. Get as much memory as you can afford.
Number of inputs, minimum of 2 but 4 is better.
Rear USB/serial port is a necessity if you wish to hook it up to a computer, large-screen. a ethernet port is not absolutely necessary. Front mount USB port is. this allows you to update the oscilloscope, and record events.
The price of a digital oscilloscope can range from a few hundred dollars, to several thousand.
Because we don't know what you are going to do with it, nor do we know your budget, we can't really tell you what the best scope will be. Do your homework, and hope for the best. it's very disappointing when you buy something that you think is going to do the job, Only to find out that what you bought is not quite up to the job. You say to yourself, if only i spent a little more money I could of had this feature. Been there done that, and probably will do it again, and again..
good luck on your purchase, and enjoy your new hobby.
