I'm going to get the OF 2200 CMS down the track. I have the OF 1400 - and I think that's big enough for anything I want to free hand or use on a track (though the OF 2200 with the interchangeable bases looks pretty smock for the tracks).
Won't be doing that for a bit though ... will probably get the VS600 and OF 1010.
What sort of "big stuff" do you intend to attack with it?
