again - the word "poseur"
get what fits your riding style and needs (functionality). asking what others think is cool is a far from truly enjoying something like cycling, and even more so, cycling on a fixed gear bike.
do you call other people before you get dressed to make sure they like you outfit?

Just trying to make a point that this is something for YOU, and no one else. Ignore all the "do this, buy that - to be cool" hype.
If the Bianchi is too pricey, the Gunnar is way out of reach. Bianchi, KHS, Mercian, and I am sure I am missing a few pre-builds - these are becoming the gateway into fixedgearedness to most newer gear riders. And there is also the school of the building/conversion - finding an appropriate frame (re: long horizontal dropouts OR track styled fork ends) and build it up as you see fit, piecing it with components comprised of form, function, and price. The latter style offers insight into the parts that make up most fixed gear set-ups regardless of the frame style and you will learn along the way. I have done my 3 bikes in the latter manner, each one close to my heart and riding style.
It is a personal decision - do you have the time and patience to build one up to meet your style? Or has the bug bitten you hard and deep and you need to pavement beneath a fixed gear pre-build NOW? Both styles of rides are well represented here, so check around using the "search" function as there are a lot of responses on this topic.
Either way, you are on a bike, enjoying the scenery and the ride. And maybe afterwards, a cup o' joe or something with a little booze in it. Or not. The choice, ultimately, is YOURS!
