I have to agree with the statement that there are better boards than the Vapor for less than the Vapor (even an on-sale Vapor). Don't mind us taking a few pot shots at it, however, we're mostly just jealous.
However, that being said, the Vapor is a killer board and I sure as hell wouldn't pass up an opportunity to ride one. If you've got the CO2 EST bindings and a Vapor, I can only imagine that this Ferrari package came with Ions or SLS boots.
Now, as far as going out and buying equipment after your first run out... Guilty here too. I came home from my first time out and my family thought I was addicted to crack or something. In one night, I went from not having the first clue about boarding to not having the second clue about boarding, but knowing I needed
more of it, like oxygen.
The next day I was on Ebay, staring at a used board package that had my size board, boots, and bindings all for a steal. I was a student at the time and didn't exactly have the money for a top-of-the-line setup, but I think $200 for a Canyon 168, Moto 14, and SI-X bindings was a good deal.
I've moved on from that package to a Titan TX, K2 Cinch bindings, and Vans Cirro boots, but it served me well. If the vapor isn't throwing you any curve balls, then obviously you got a board that works for you. Not just that, you've got a board that would work for just about any boarding Olympian as well.
EDIT: I didn't see anything about you getting helmets
for you or your daughter. You may want to give that option serious consideration, not only are you beginners, but it's just a good idea.
EDIT EDIT: If you ever find you don't want any of that equipment, let me know.
