I realise the FT site has a ton of bells and whistles and extras etc, but am I seeing this right that a single vBulletin site is only $160 a year for full licence version?

I have thought of setting one up for the field I work in (postage stamps) and thought it would cost lots more. I have my own business website with 250 different pages, and I presume it can be hosted on that site, but know nothing much about tech stuff. If it attracts a few 100 members I guess that does not consume a lot of bandwidth if graphics/image posting are turned off like on FT?

Anyone set one up .. i.e. after you pay the $160 is there a pretty easy set-up required?
