I'm looking for a strong, decent, lightweight (steel, aluminum if possible, optional) frameset with the top tube sloping forward towards the stem (not sure if I described that correctly, sorry) in the 100-500 price range. I love the feel of my Montgomery Ward conversion, but I feel like it's time to upgrade to a real track frame and as my bike for the rest of my life if I like it.

Any recommendations are appreciated, thanks for the help in advance.
