Meru, sorry for the late response. I don't have personal experience of the Unitec but seen them in the shops. Even their SWAT-200 is quite hefty. If I hadn't invested so heavily in my Polarie with options, I probably would have gone with Unitec.
They're really configurable and can even carry small scopes (as pictured below...their SWAT-300/350 can carry even more but by that time you may as well have a proper scope mount) :-

There's no GOTO but there's autoguider capability.
