Rebadged GW Instek ones. Probably go for more than they are worth at those things. Anyway - DG822 arriving tomorrow so too late now
DG822 can be cracked to turn it into a DG922 which will give you (with some calibration error) 100MHz arb worth a few quid more https://www.rigol-uk.co.uk/Rigol-DG992-Waveform-Generator-p/dg992.htm
Edit: also DGxx does two tone one one channel which means you can do linearity testing easily.

I did the upgrade and for someone like me, living in less-than-100-MHz-two-significant-digit reality, it was a bargain. The biggest interface problems: the touch screen is a little squirrelly and the power button is just plain stupid: too small, upside down, and in the wrong place.
Plus I can still pull out the 6061 or an 8460B if I really need something more...
Only thing I haven't figured out is how to keep the upgrade and update the firmware to take advantage of a couple of recent bug fixes. Have to go back and read through the thread here on that one more time.
Yep it certainly is a bargain. I did consider going with the rock bottom 10MHz single channel unit and cracking it straight away but literally I need an audio, 80m, 40m, 30m, 20m band signal generator and it was ~£50 to get an officially sanctioned 2x 25MHz optioned unit which wasn't worth arguing with now. I figure if and when I need more megadoodles it'll be worth the couple of hours to crack it at that point. As it's from Telonic it'll have been updated before it arrives so I'll wait and watch the firmware thread. I expect the touch screen to be wonky and in fact I bitched fairly heavily about it on the forum a while back. Worst case there's LXI
I would love an 8640B but the gearing and the failure rate scares the crap out of me. I have used Rigol DG1022Z pretty heavily for about 2-3 years now on and off for RF'ey tasks and they're good enough for amateur radio use on HF. Probably not lab grade but it makes a perfectly acceptable LO for example. Not too fugly phase noise. DG800 is similarly spec'ed.
Hopefully the counter in this isn't a piece of crap like the DG1022Z but I don't hold much hope. Not buying it because it's a counter though.
Mini rant about NanoVNA here. Hit a wall. Absolutely useless for crystal characteristic measurement due to the min frequency step. Another reason I need this...

Those Rigols sound like fun but I can't stand the look of them.
That sounds like my marriage described succinctly from start and end

Edit: have put a SDS1202X-E on the TE budget this year. To the dark side it is.
