The problem with HF's smallest is, based on my experience, that the SCFM (flow volume) is too low and the max PSI too low to be a reliably effective tire mounting tool, and then to only spend $20 on hose and attachments, you're just building a crummy, ineffective system that will compound frustration. I mean, it might work for some combos and may be worth an $80 flyer for some, so one would need to weigh up the risk of blowing the time and money on it.
