This is the kind of stuff where the "big two" might initially laugh and scoff. A few years down the road that might turn into "Oh dang!". Remember when the first VW Beetles showed up and the top managers from the big three had a major ROFL episode? None of them laughs anymore.

They don't have much of a rep - yet. You are much safer going for a similarly priced Rigol unit (cheaper in fact in this case). They are proven performers and decent quality, which is why Agilent rebadge them.
Or perhaps one of the newer 1000 series Rigols if your bandwidth requirements can be lowered.
Don't know anything about their scopes but I bought a Uni UT60 dvm from Marlin Jones
a few years ago and I'm happy with it. Haven't needed any service but they offer pc software to datalog with this unit and their (Uni's, not mpja) website had a busted link for the download that they fixed within a day of my sending an email pointing it out. YMMV, of course, but I got my money's worth :-).

That Instek GDS-2204 here on the bench runs circles around similar Tek scopes. Not just because it has ten times their storage depth. Engineered in Taiwan. I bought it not because it was cheaper but because it was better.
Remember when engineers said that flat panel displays will always be a domain of the western world? Go to CostCo and take a look around ...
I agree. The 5000 series is an older model, almost discontinued. But at least they have a good rep and their scopes work well, but the newer models with deeper memory are more expensive than the OP's Uni-T price point. Uni-T brand, hmm, no one has posted a review yet that I am aware of. I'd be surprised if there weren't at least a few firmware bugs.
No idea. Perhaps send Uni-T an email enquiry and ask what their policy is about releasing firmware upgrades. No response = warning. Might be mentioned in the manual, worth a good read before making your decision.
