Hello folks
Not sure if this is the right section to post but I'm looking for some opinions about Digital Oscilloscopes.I want to buy one but the market is flooded with different models with different  frequencies so I'm not sure what is the best for me.
Can someone advise me what points are important in this  moment of choose?
Sure the bigger price are best but perhaps I don't need a Top Scope

1) What exactly do you need to measure?
2) There is no 2

Well I want to measure some arduino PWM signals and I also do some Tv repairs and monitors.
The logic analizer would  also be important feature

The main  criteria when buying a scope is what is it needed for. What frequency ranges do you need to measure, how many channels do you need, does it need to do analogue & digital (yes), does it need to be a storage scope. Beyond that comes considerations like cost, how heavily does it gets used (pointless buying small cheap scope for continual benchwork) does it need to be portable (maybe battery powered)

There is no such thing as a stupid question but there are a lot of inquisitive idiots.

What's the min/max frequencies, voltages?

How many channels do you need?

If you only need two channels and 100mhz will do it for you, a very inexpensive scope that is of very good quality is the Rigol DS1102E

http://www.saelig.com/PSBE1002/PSPC017.htm

A better scope seems to be the Agilent DSO2002A which is about $1300 for 2 channels @70mhz but it has double the sample rate of the Rigol, a much better display, and a lot more features.  It can be software(!) expanded to 4 ports, 200mhz per port, and an 8 channel logic analyzer that is synchronized with the analog side.   With all the goodies it's about $3000, though.

Thanks for all answers in special to JoeN
I was looking for that answer. The scope Rigol  DS1102E it seems to handle the job. I also found a comment on EEVblog  describing it.
I will search for more info about it
Any more models and opinions are welcome

Look on ebay and craigslist and such for a good used scope.  These are usually a great bargain for a hobbyist.

Stay away from the cheapie pocket scope things, if you have any interest at all in analogue performance.
http://www.eevblog.com/2010/05/11/eevblog-86-buy-a-real-analog-oscilloscope-please/

Get the Rigol.  It has a good price and good reviews, even from folks who are really interested in high quality analogue performance.

Don't tell anybody I told you, but... apparently the DS1052E can be changed to a DS1102E via the serial port.

I've recently acquired a ATTEN ADS1102CAL+  - which sounds like its related to that Rigol model - has 7 inch screen which
is really nice to have.  100MHz, 2 channel, 1GSPS, etc etc.  No complaints so far.

Amazon I believe, 'bout £300 UKP.  Seems to be popular and going down in price since I got mine ...

RIGOL OEMs it to a number of companies including ATTEN.
