a frame is a frame. Its just tubing and welds. If you like the look of the frame then I say do it, because buying a 900 dollar bike gets you pretty much nothing. if you spent 950 on a kilo you would have one hell of a bike with really nice components and it would ride and feel better than any stock bike you could buy for the price.
I say do it in shifts though. I would buy the kilo first, then start swapping/stocking new parts. This allows you to enjoy the bike in its simple, stock form, all the while upgrading it along the way. This also helps so you can see if you like the different components together. How did you get to 950 bucks by the way? Parts list?
