I agree that $1500 is a lot to spend on a fixie/singlespeed that’s just going to be ridden around on roads and trails. It’s probably best to try and find a bike that can clear at least 28mm tires (the max for standard rim brakes). That’s a rarity with track bikes, since many of them use the narrowest tires they can find. Many won’t even list tire clearance because it’s largely irrelevant. Many SS/fixies will also have very aggressive geometry, which is quite fashionable or even useful on the track, but can get quite old for someone who is just riding around at a low intensity.
However, if you still want a light, fast fixed gear bike, the ribble eliminator seems like a good option that isn’t very well known (I have no experience with it). Stock, at $700ish, it weighs in at 7.05kg with no brakes or pedals. Add both and you’re looking at around 7.5 kilos. If you’re willing to splash out, you can build a nice alloy wheelset with Miche EDIT: Mack* hubs and chop 800g or so off. That will bring you to 6.3kg or so, which is extremely light.
The state bicycle co undefeated is a more well-known option that might weigh a touch more.
