Any modern GPS, especially one in that price range, ought to be EGNOS compatible.
My Garmin 496 certainly is, but quite often it doesn't seem to be receiving it. It seems about 50% lucky, despite having a remote antenna connected.
I got this interesting pic last year, but didn't make note of whether it was on EGNOS or not...
That level of vertical accuracy is not in itself exceptional; even my old KLN94 usually shows it within about 10-20ft of a known elevation when on the ground.
