Spending "too much money" is relative :). $2500 a year is not that much to me (just sunk 14K on a home theater and I just chose not to go with my local BB since they didn't have a Magnolia store). This purchase though gets me about 1/2 way to silver status. Glad to hear that it worked out well for you!
I bought the one from Target as well (and is the one that I am already wearing out the F5 key on as we speak). I like it alot, the only thing is that the keyboard and touch pad size size is taking some getting used to with my big bear claws.
