Thanks again glangston.
Well I went to the holy land today, that being B&H, I had been there before a long time ago, but wasn't into photography then, just looking around. It was awesome. They have this Canon section with all of the lenses there for demo purposes. So I asked the guy for the 1.4 extender and 70-200 L lens, he says "What camera body", as they had all of them sitting there, I said rebel. Tried it with and without the extender and noticed a considerable difference in range, so I bought it. I also bought the tripod ring and finally got myself a rocket blower.
It was just fun to see all the various Canon lenses. They had this massive 600mm lens, looked like a small canon 
So if you happen to be in NYC and on the west side, definitely stop into B&H, but be warned, it is very easy to spend mucho bucks. Oh and their inventory goes down 3 floors deep, at least that is what the salesperson told me.
