I got Michelle's "Wrapped in Colour" kit (I think that's the name...) and I absolutely love it! Great quality, great selection of elements. I would definitely recommend her stuff.
I also have Dianne's "Petals and Patches" and love it, too! Wonderful texture in the backgrounds--they really look like cloth. I have a layout I did with it, here:

Unfortunately I haven't gotten around to posting my Michelle layouts yet.
I haven't bought many kits yet, being new, but so far I haven't been disappointed with anything I've purchased. I find that a bunch of Traci Sims' stuff is on my "want-to-buy" list, if you want to check her out.
I keep looking at the gallery and thinking, "Ooh, what kit did they use for that?" and bookmarking everything I find.
