Ray, check out <a href="https://www.rocketwarehouse.com/Aerotech/Starter_Kit/starter_kit.html">Rocket Warehouse dot com</a>. I know the owner personally. His name is Jorge and he used to sell and fly rockets at the THOR club. He's a very nice guy. His website currently lists the Aerotech Initiator Starter Set as being In-Stock, but you might want to call him first before you order. He lives in Brandon, so it actually might be worth your while to just order from him and pick it up. (Save on shipping and the possibility of not being in stock.) Tell him Eugene w/ onboard video from THOR sent you. He should remember me although it's been over a year now.
I can vouch for a2z. I've purchased from them before and they've always delivered on time. Since you are purchasing a higher dollar item and a set that has been low in production lately, be sure to call the vendor first and ensure they have it in stock before you hand over the payment. Chances are, if they don't get back with you right away or at all you may hold off. All the links Zippy offered are very reasonable vendors.
Good luck! I am extremely excited for you. I remember the feeling of getting started into mid power. You won't be disappointed with Aerotech rockets either. Very nice to build.
