If you have a welder you can build one for way less than 400. I posted a thread here with the material list,dimensions and lengths and instructions. Not sure how to post the link but will give it a try.
I was looking for something like that as well. I've seen plenty of threads/pics of people building their own but no real details. I can't weld but I may be able to convince my dad or cousin to help out. I'm still in the market for one if someone wants to part with one for around $200. Got more money than time at the moment and just want to see this thing done.
