Which electric E6-B would you recommend?
None, actually. Your original post makes it sound like the information "written" on your E6-B is factory-printed. Should be totally good for the test. If it's a bunch of sharpie handwritten notes that someone put one there, no-go. You have everything you need to learn the calculations, pass the test, etc., without getting an electronic calculator, all the way through ATP certificate if you choose to go that far. OK, caveat, a simple arithmetic calculator, even the free solar ones from the bank, are good for weight and balance problems. Real-world bottom line, once a licensed pilot, you'll be using Foreflight, or any of the dozens of other flight planning apps/software, combined with on-board avionics (GPS, fuel totalizer, etc.), for your everyday requirements. But, for training, the old school whiz wheel is just fine. That said, if someone had "gifted" you an electronic E6-B, that would be fine, too. Either way, post-license, it'll end up in the lint-filled bottom of your flight bag.
Another caveat, I'm an old fart, long-time CFI, but, I can't tell you how many students I've had, coming from some other flight training operation with an electronic E6-B, perhaps getting the correct numerical answer to some problem, that were completely clueless with any fundamental understanding of the principles concerning fuel burn, wind correction, ground speed vs. true airspeed, etc. Bottom line, you're all set, learn the stuff, and go fly. (OK, Lewis Black rant off, time for a nap.)
P.S. To your original question, if the info on your E-6B is factory-printed, good to go!
