The aviation college here in Adelaide South OZ have dozens of them (Tobago's) used to train international students for mainly the asian airlines. While I haven't heard anything bad about them from a maintenance/ reliability point of view I was told if you are a 6foot plus type person like me you will have trouble with the headroom in them, though I did sit in one once and it didn't seem too bad.
One thing I can tell you though considering they have a constant speed prop they are fairly gutless as my Archer 2 will out climb them and I usually end up slowing down behind them if doing circuits. Whether this is due to the student pilots or not I don't know but doubt it as I've heard simular stories. So whether you would want the extra expense of the prop maintenance for little if any gain is questionable.
