Thanks for all the quick advice.
I think I've pretty much decided that the E3 is not for me. I'd rather have something that flies in a closer style to most other high end stunt kites. Either way, it definitely doesn't have to be a Prism kite, and it's good to know HQ is at least a trusted brand.
The Kymera also looks to be available on Amazon. I know people are pretty biased around here :-), but it does seem to be right in my price point sweet spot, and it's gotten lots of good reviews on this forum when people ask for advice on where to go next.
Any thoughts?
P.S. It says on the product page for the Kymera to use 90-lb lines...does that mean it doesn't come with lines? The only other kite I have is the Prism which came with lines and handles. Any good places online to pick some up? Should I only use 90-lb lines of any length? (/noob questions)
