The 7000 is one that is overlooked, with the help of certain astute members of this forum the 7000 can be turned into a really good scope for a sensible cost.
Remember 10G/s + 500M of memory makes for good debug, it now has high resolution and precision functions, plus a 10 inch screen some useful tools plus an hdmi out.
We have one of these in test lab and it works very well, we also have an 8000 which is a real serious model. We also have Siglent, HP, Tektronix kit as well.
The Rigol's hold there own in a lot of areas, as I have mentioned before no they are not upper mid point top five brand scopes, but they do a lot right and the 8000 has some decent noise figures in certain areas that are equal to or slightly better than some of well know long established brands we have entertained recently.
We now have a LeCroy wavepro to bench test so we are lookig forward to that, however the Rigol scopes and RTA are damn fine for what we require and our staff like them and some of them are used to big ticket ticket items.
I occasionally curse the 8000 boot up time around 50 seconds , but the Tek mso64 took around 5 minutes to boot up. granted it is really an R&D scope and not an everyday bench item.
The 7000 you get an awful lot for your money, though I would suggesting investing in a couple of good probes,. Rigol also manufacturer a Tek to Rigol adapter as well.
