It's all about your budget. The Bianchi Pista and the Fuji track bike are nice and cheap. The IRO is probably the cheapest frame you can buy. I test rode the Langster - it was HARSH. It also pinged every time I hit a bump. I ended up building a Steamroller and I am very pleased with it. It handles sweetly and has plenty of room for fatter tires even with a front brake since it uses a long reach caliper brake. I'd go steel even in a wet climate, it just feels better. If you build your own, be sure and coat the inside of the frame with linseed oil or framesaver to prevent rust.
