i got mine (bogen) at micsupply but i think you can find a better price...however they did have a package deal and you may want to ask about that.
you'll need a t-dar at the very least, but i highly recommend getting shockmounts also. sabrasom will do the trick and are very versatile but break easily. at8410's (the ones with the clips) will works great....you can also pick up a set of tensamounts for like $30 for the pair, much cheaper than either of the above.
