I've never bought a kit. I like doing my own thing. So, does the kit include just the fabric for the top? If so, it seems very expensive to me for 53x64 quilt, even in batiks. For $75 I could make a king size top. I could buy 10.5 yards of batiks at Connecting Threads.
I agree with those who said to pick your own fabrics. It would be cheaper and picking fabric is the most fun.
