I used a suspension fork off a walmart bike I found in the trash for months with no problems. The fork did have a lot of slop in it, but I took it apart and put it back together and that took care of it. I've since built a different bike, and switched to a pair of motorcycle forks I got on ebay for $50 shipped. Too many people equate quality and price, thnking that low price always means low quality. Sometimes that is true, but you don't need to spend $150 to have a safe bike. Look around on ebay and see what you can find.
