I love both Keepsake and Connecting Threads. However, with Keepsake a couple of my quilts didn't have enough fabric.
It took a few emails/phone conversations to get it straightened out but they were the best! I found out they stack their fabric when they cut it. So, if your kit is from fabric that is in the middle or bottom of the pile it may not be straight.
My suggestion is get a kit, open it up and look at the fabric asap. That way you will know if you need replacement right away before they run out of fabric.
