I can't comment on how hard it was to clear the bonus (I don't remember how I trackedd it, but I cleared $100 easily enough), but it's a good site. I don't play cash games there, but they have decent tourneys. Their interface still bugs me a bit, but you can not pass up the overlays on ALL of their big tourneys.
Definitely worth checking out. And I may be able to give you a little sumthin sumthin too...
