Hmmm. Unless your wallet is simply hemorrhaging cash, and you have to find a place to put it, my advice would be to prop up your feet on the couch when you get home and let your mind and body REST. You are going to burn out, at this rate.
As a newbie, your enthusiasm is wonderful and expected -- I think we've all been there -- but you build up your aikido "vocabulary" over time (they call Iriminage the Twenty-Year Technique for a good reason). Let yourself relax, enjoy life outside of the dojo, and you'll be much better for it.
On the hippo-critical side, if you are hemorrhaging cash, buy them BOTH and do a technique by technique comparison
