Plus the new Siglents are huge - as big as the previous generation where the Rigol is small/cute.
Okay, I get that you love Rigol and love to hate on Siglent, but this is a bit much.
Neither are on par with legacy CRT scopes that were two feet wide and three feet deep and weighed 90 pounds.
The Siglents aren't "huge." They're still quite compact for what they offer, and while I don't have confirmed measurements at hand, I'd expect their area is comparable for similar class of scopes. The SDS1000 adopts the newer vertically stacked design with BNCs shifted left below the screen and fewer controls to the right, so they are taller but also more narrow. The SDS800 looks to be very similar in size to the SDS1104X-E (I've heard claims it's based on the same mold) and Rigol DS1054Z formfactor. None of which are "huge." I have the SDS1104X-E sitting beside the DHO1074, and by comparison the DHO is "huge" -- which one would expect given it's 10" screen.
If I want small/cute, I'll grab one of my portable handheld scopes. The DHO800/900 is right in that weird space that's too big to be a handheld and a bit too small for a bench scope with a touchscreen UI. For my bench, I *want* a larger touchscreen. I have the Rigol DHO1074 and for me it's the perfect size for a touch UI on the bench and not large at all for a bench scope. Now that I've used it, I honestly don't think I'd be happy with either Siglent's or Rigol's 800 class scopes with their smaller screens. If the emphasis on UI is moving to touch, then the screens MUST be larger.
I bought a Siglent electronic load, it was riddled with bugs and the fit and finish was horrible. I sent it back and bought an Instek which is very good but it cost more. You get what you pay for I guess, I'm used to Keysight, Tek and other better brands. It's a tool, I don't want too many work arounds or I dump it.
I honestly don't think the DHO800/900's are that bad and I like the footprint, if it was a bigger scope I wouldn't have bought it. The fit and finish is pretty good too.
Apart from the Rigol fanboys, I think most will acknowledge that on a quality and professional scale, Siglent has been pulling away from Rigol in this mid-tier category. In the beginning, they were strictly budget tier, but now are positioning themselves as being more pro than Rigol, encroaching on the territory formerly dominated by the top tier HPAK/LeCroy/R&S brands. Sure, Siglent has had their stumbles, but so have all the others. And Rigol seems to stumble more out of the gate where Siglent is usually more polished at release now.
I would definitely rank Rigol above the Hantek/FNIRSI/OWON brands but also below Siglent.
I have the Rigol DHO1074 (fully upgraded) and there's a lot I really like about it, especially for the BF price I paid (I don't think I'd be nearly as happy if I'd paid MSRP though). I like that Rigol is pushing the market to respond and be competitive on next-gen capabilities, even if they release premature products to do it. But I also own several pieces of Siglent gear including an electronic load, and I have few complaints about any of it. It's been great. To be honest, I'm happy enough with my Siglent gear that I wouldn't have even considered Rigol if Siglent had an answer to the DHO1000 series at a comparable features/price point. Should the SDS1000 be released at a good price point, even if a bit more than the DHO, I'll most likely be trading up to it.
