The 3E series is... underwhelming, extraordinarily underwhelming.
There are plenty of people that own them, and enjoy them; more power to those folks, everyone should get every bit of enjoyment you can squeeze out of machine operation. That said, until they bring it up to par with the Kubota L02, Kioti CK20, TYM 15 series, Massey 18E, or even the the Mahindra 1600 series, I wouldn't touch one. I, personally, think the LS MT225E could also use an update, but it's not as far behind ergonomically as the Deere, it desperately needs more operator room. Well, to my tall, fat butt anyhow.
Now, the 3R series, I like them a lot, but that's a whole different animal.
