I concur on this point. An option to choose whether to use the old style or the new one would be ideal.

Truthfully, I know that a fair bit of time and effort must have been spent on this, but it does not have the same charm as the previous UI did. It feels more like it's trying to be too much like some of the other trading sites out there (especially those like Bazaar.tf) and losing the charm that made it Outpost to begin with.

I too am rather fond of the old style as it set it apart from other sites such as dispenser.tf, and it was easy to traverse and visually ideal. I would prefer the old style over this new one in a heartbeat.
