ANd GDS-2000A has no fine vertical scale setting. Why?? And even no pushable rotating encoders. But it's still an interesting scope. As seen in the datasheet: It has a three year warranty - but excluding the lcd panel. Oh why?
The pushable encoders isn't really a big deal. Pretty minor actually. The warranty is slightly more annoying on the LCD - and I have a question out to their US sales team asking why this scope isn't limited lifetime like their other gear.
The lack of fine scale vertical is more annoying however. Still, you can get a 2204A for about $1765 here in the US which is a fair amount of scope for the price. The 16 port LA seems to cost about ~$800 and I believe it comes with all the decode options as part of it. So base it's about $500 less than the Rigol 4014. Not apples-apples again (Rigol has way more memory, faster sample rate, faster wfm/s published, etc) but the Instek has the built in LA function. One other thing though that caught my eye is no 50 ohm option on the Instek, it's 1M only.
As usual it all kind of depends on what your application is to determine which scope. If the Rigol 4000 had a published upgrade to add the LA option to the existing family of scopes it'd be almost a no-brainer but they don't, so it isn't.
I will say that the Instek response has been decent - sales response took a day or two but I did get a response as I noted. Admittedly this is in the US so YMMV based on your location.
