I'm planning to - eventually - buy an NS NXT 5 as well (LH version, currently just under a grand from Thomann), for exactly the same reasons. The RH version is just under £900, again from Thomann.
As for its size (or lack of it), my experience with my present cheap upright is that you do need to use the bracket or whatever "thingy" they supply, as it helps you keep the correct distance and angle and avoid hurting your arms and wrists. Other than that, the EUB should be fine, although not easily comparable to a DB, simply because it's got that B string and, presumably, electronics that are optimised for capturing and delivering the frequencies it outputs. Oooo I'm in lust
