Assuming you're mature enough to ignore the labels, stereotypes and pre-conceived notions that flood this board (and young minds alike) surrounding Pistas and fixed riding in general...

The Pista is a great start. It is affordable and of sufficient quality and appeal that resale would be no problem if it isn't for you.

Don't over think it. My advice would be to go ride one around the block. You'll likely end up buying it, enjoying it and figuring out the rest on your own time.
