Welcome back. unfortunately kiting has declined since the 90's. Manufacturers aren't as numerous, especially in the US.
Definitely check out Lam Hoac's kites. He enjoys conversation and is very helpful.
I also like my LumoKites by Antonis Loumiotis
A lot of top flyers are making and flying kites based on open source plans http://www.kareloh.com/kite-plans
I've been told that Krijn Hemminga can make a lot of the open source sails and you just add the hardware.
Check out Virtual Freestyle for some great trick performances and to see what kites top flyers are competing with http://vf.kiteclique.com/
