Zero. It's a Chinese special. You can likely find most components at Princess Auto. Replacement cylinders and what not. As long as the pump and final drives are of decent quality then you shouldn't have too much to worry about. You could rent a machine like this for $500 a day so you can have the machine pay for itself pretty quick as long as you don't let any idiots on it.
There are 20 of them going across the block as I type this in Toronto, then on Saturday a bunch more in Edmonton. Frontier offered a price you would be hard-pressed to get at auction after taxes and 10% buyers fee for items under $10k. I was expecting to see $9k when I clicked the link.
