The main question was, is it fun? The answer is a resounding YES! I recently got back in with the MK II rule change (Jan 2010 if you didn't know) and I'm enjoying the new rules a lot more. I really like the miniatures, there are a few, as in any range, that I'm not a big fan of, but very few that I actively dislike and a lot more that I think are just awesome.
If you've got the cash you should definitely go for it as it is a lot of fun to play.
