That would be very interesting, Can you provide any URLs?
Such as? I'm not challenging what you are saying but I'm trying to make a buying decision, so I'd like what ever specifics I can find. From what I've read, the logic analyzer option for the scope had a bunch of problems. I've recently tried to comb through the 50+ pages at rcgroups and the 14+ pages at eevblog and I didn't really come away with that impression other than the logic analyzer issues. Maybe I didn't understand enough of what I was reading.

I bought online on eBay, and apparently Rigol hates customers who bought online and not via an official distributor with inflated prices.
Very annoying is also Rigol's habit of declaring models as obsolete when they no longer want to maintain the PC software. "obsolescence" is at least their standard explanation for lack of Windows 7 software for some models. See below regarding Linux software.
Rigol: A mess to get it working under Linux.
The usbtmc kernel driver doesn't work for me. It always fails already when trying to open the device. The Agilent kernel driver doesn't work, because it uses old internal kernel interfaces no longer supported. The openmoko libusb driver? Well, after I used it as a model to write my very own driver, I have a libusb driver working 9 out of 10 times. Sometimes the instrument's USB port locks up, requiring to cycle power.

You could include specs, pricing, impressions, etc. Long threads stop being useful to people if they have to slog through numerous pages and the information you guys are providing is too valuable to have it end up buried deep in a random thread.
