Hello, I'm heading off to college and I need a daily beater. I've had a custom 8th inch fixed gear before but it got stolen a while back So, I'm looking for suggestions! I'm thinking of getting a Critical Cycles or Pure Fix off Amazon and calling it a day, or I can custom build one from scratch if it's a cheaper/better route. I also found this on craigslist:

Brand NEW fixies [50cm 54cm 58cm] [FREE tools] Delivery Available!

My budget is $250, cheaper is better. (So I don't feel bad about it if it gets stolen).
Feel free to post links to eBay frames, brand name bikes, etc!
I'm not really in the market for a used bike, but will lightly consider it.

Thank you, have a nice day.

This probably won't be the answer you're hoping for, but frankly, there's not a lot of difference between any of the sub-$300 ssfg bikes out there. If that's truly all you can spend, just pick the one that looks best to your eye.

If I was in your shoes, I'd start by trying a fit calculator so you get a general idea of what frame size you need, and then head to craigslist to see what the used options in your area are. In most decent sized cities there's no shortage of PureFix, Critical, and other budget bikes being sold by folks who bought one on a whim and realized they either didn't like ssfg or immediately wanted something better. And there are usually nicer bikes on cl that will be closer to your budget since they're used.
