How does the price compare to other retailers, when you factor in the fitting too?
If you want a power meter, if you want that particular power meter, if you think it's a good deal for you and if you have the money, go for it.
Only you can decide if it's a good deal, purchasing is not only a rational act, it's also emotional (if interested in such things, buy a book on branding to read while turbo training

)
For me it's an awful deal and a complete waste of money, but then I'm not in the market for such things
