Just wandering. I seen them on youtube. They look like they could be cool if you have a lot of free resources. To me it looks like it would be cheaper with your time and material included to just buy by the ton. I am just asking if anyone owns one to give me some extra info. I have seen one on a local add for around 3000.00. I haven't done any research on prices so let me know if this is in the ballpark. Thanks
