Cool! That's a sweet looking little axe. Lightweight, P-90's (I have always loved P90's but never played them on a strat). Played a Les Paul with P's and (although they were a little noisy, it was an older model) I loved the tone. The newer P's are much quiter. That guitar should give you a sound that is much different than a normal Tele twang. Although P90's are single coil PU's, they sound very different, in my experience, than the PU's in Strats and Tele's. The only thing I don't like about that guitar is the neck radius. I have a Strat with the same radius and it's difficult to bend strings (versus modern neck radius's which are larger, giving you a much flatter fretboard). Some people, however, love the old-school radius because it's easier to play chords. Guess it's whatever you are used to.
The deal looks good to me. I'd rather pay a bit more for something in good shape, than save a few bucks and regret it in the long run. That guitar looks solid and isn't too heavy which I love. Best of luck!
