It also helps to have a large flash.  At high magnifications a
larger flash head (meaning the lens for the output) can act as
an equivalent to a softbox.  Let's face it, if you were
illuminated by a flash which was two or three times as tall as
you, any "point source" effects would be eliminated, which is
the function of a softbox.

I use the 280T on the Hotshoe Grip and attachment brackets,
which can be manipulated so that it is adjacent to the front of
my 90mm macro lens.  A 200T on another HSG is chained to that
and used hand held to provide fill.  This has the bonus of
supplying a comforting beep to let you know that enough light
was received for "correct" exposure.  All purchased secondhand
for a total not exceeding �150.  Allowing for "rip-off Britain"
you should be able to get it for about half that.  

I recently used this and my 50mm with bellows to photograph
~3-6mm bugs (Hemiptera) on 100ASA E6 for a friend's thesis. 
Perfect exposure.  Focusing was a learning experience but we got
there in the end.

If I wanted to use the 200T on an attached bracket I would just
buy another attachment bracket and stack it under the first. 
Usually, what I want to shoot is immobile enough to not need
this.

I repeat; big flash is good for macro.  I have no exposure
problems with Pentax brand flashes used at ranges of 3-10cm from
the subject.
