There are plenty of things you can do to a SD3, but the E3D is not a "requirement". In fact nothing is a "requirement", the printer will print "out-of-box. Glass is indeed a cheap upgrade and very convenient to clean, but I'm not sure where, or when the E3D became such must have upgrade.
You also may want to mention that in order to do that upgrade, the user will have to be able to print a E3D compatible extruder first.
I'm probably gonna get flamed for this by the E3D believers, but unless you plan on printing other materials (nylon perhaps), I personally don't see the need for it. I have the original hot end, and it works just fine for ABS. I have no interest in PLA so I can't speak for that, but for ABS, the original works just fine.
I can think of plenty other upgrades I would do before changing to an E3D, especially if the original is not broken.
To print or, 3D print, that is the question...
