I'm getting my first fixed gear, figured I'd start somewhat inexpensive and just upgrade parts as I get to know it better.

These are similar prices but I don't know how to tell which has the best parts or is best for a newbie.

Basically just want something light-weight, simple, good ride.

1) Windsor Hour
2) Mercier Kilo TT (I was originally going to buy the Kilo TT Pro, but they sold out )
3) Motobecane Messenger
4) Motobecane Track
