Never heard of Galaxie. But the cheapest brand new common fixed gear bikes like Purefix or Retrospec start out around $250, and Craigslist asking price for entry level bikes of that nature (used) are between $160-200. Considering your short commute distances and if you aren't looking to catch the "addiction", it seems like on ok starter/commuter bike, not great, but putting into perspective it's intended use, you'll be alright if you are willing to adjust to fixed gear riding.

Normally I'd say look at Craigslist for opportunities but you're not going to know what to look for or how to maintain/fix a second or third hand bike and you could be waiting a while before you found a good condition quality used bike that comes in your size.

Basically $250 is a pretty small budget, options at that level are all going to be mediocre at best.
