Fun kit
I purchased the basic kit at a beauty store and just tried it out today.  I like it.  The designs come out nice and it is super easy to do.  Yes, I do think it could be a bit less expensive, but it will be used enough times to get my money's worth.  My 11 year old daughter was the first tester and her designs came out nice.  I saw the other review about not being able to expand, but it comes with a dvd and a booklet that lists all of the expansion add-ons, including many other designs and polishes.  I recommend trying it out for yourself. I think you'll like it.
