So we all lose, as there wasn't an option for "buy one of each"! Now that you have them both (and presumably have used them both a bit), how do you feel about your original question?
Well, I bought the DS1052, and work bought me the DS2072. =) So, it's still valid. =)
I really liked the DS1052e. It worked. It was simple, did what it should, and was really inexpensive. Used it to fix several pieces of equipment.
Yes, the DS2072 is better. Is it worth 3 times as much? I don't know yet, but with how much I've used it, maybe not, at least for what I do with the scope (electronics repair). Yeah, a $100 analog scope would have worked too, but I never found one I really liked for that price point.
What really muddies the waters is the new DS1000z series. 4 channels for $500 (if you include the tequipment eevblog discount)! And for not much more, you get an AWG. Crap, my bench (shelf) would be much less cluttered! =) I haven't used one, so who knows... but given the specs, I wouldn't hesitate a moment if it was my money. I'd grab the DS1000z and never look back.
But, if you only have the $300 like I had... I wouldn't hesitate a second to get the DS1052e unless you have some big need for the extra features of the higher end scope, or just hate buying older tech. The 1052 served me extremely well. I'm still not sure if I'm going to sell it, or keep it around (I could easily use it as another two channels by linking it to the DS2072).
Hopefully that makes sense. I can't really speak to the difference if you're doing higher end work, but for repair... depending on what it was, you could probably buy the 1052e and make that money back just on the hours billed for the repair. =)
