Budget portable handheld dso 211vs 212 vs 213

I'm busy trying to decide which DSO model to buy. Amongst my options, since the DSO203 no longer seems to exist, when I do a search I find the "updated" models, are the 211, 212, and 213. I'm open to suggestions for other models. I'm also starting this thread in part as a place to store the info I gather all in one place, which should help others as well.
One of the most important features to me is the ability to record a pattern and scroll and zoom in to the pattern - none of the video reviews seem to go much into that because most of them are people recording continuous pulses.
The DS211 is the cheaper one of the three at around $60. The controls look relatively simple but that often means the need for digging deeper into onscreen menus.

The DS212 is about $25 more and has interesting looking controls.

The DS213 looks like the one to get and of course whenever that is the case it's twice the price of the others.
I like the look of the controls and there are options for buying tough-covers.





Another option which looks more solid though I don't know about it zoom and scroll abilities after capturing a signal?

I'm starting to lean toward something a little more sturdy with a stand. At about US$100
I still don't know about the scroll and zoom capabilities for analyzing a pattern.

I may just order one of these $40 scopes in the meantime and see what it can do - might be a good option for the apprentices to learn on.
