Hey there,
After a ton of test riding and researching, I was between the IRO and Steamroller complete...similar price and quality ranges.
Both have a really solid parts set on the complete bike, compared to Pista, Fuji track, Rush Hour (which is a step up, but I don't know who can tolerate the width of that TopTube), etc.
The Surly has a slightly longer than normal top-tube for the frame size, also it has a slightly more relaxed fork rake....if you're coming from a regular road bike, this bike will feel a little more "home-y" at first than a bike with more track-ish geometry.
The drive train felt rock solid to me as well. Personally, I'd much rather have a upper-mid quality bike to begin with, and enjoy my purchase. Rather than a lower quality Fuji, etc where I would always be thinking about how soon I will want to upgrade the cranks. If your bike shop is throwing in pedals, I say bite the bullet!
