Hi,
I for one cannot recommend you the WS3000, though I have to point out that I have not used other scopes you're considering. We have the 350MHz model with some decoding options and the waveform generator. Lecroy has sales quite often and we got this model for a reduced price and with (some) free options. It's a nice scope, looks the business, but it's really slow and can get unresponsive to the point where it's drives you mad if you have to work on it for more than 5 minutes.
If you have just the basic main screen and you're capture waveforms, it actually works great and quite fast. As soon as you add measurements to one of the channels (like frequency), the speed drop is really big. If you add a more advanced trigger, or add any of the math functions... the scope get's painfully slow, up to the point that you have to wait for a few seconds just for it to respond to a knob turn or a touch on the display.
I don't know about other scopes, but this one does all of the measurements in software, without any FPGA acceleration. It's an Windows Embedded based scope. I don't know what processor it's using, but LeCroy really should have spent more on the CPU as it's the main bottleneck. If they only spent an extra 20$ on a more decent CPU, this would have really been a killer scope.
Hope that helped narrow down the choice for you,
Regards
