As you think about your options another thing to consider about a lease is the cost of actually owning the equipment at the end of the deal. I don't know anything about the leasing company, so details will vary, but the "$1 buyout" is not automatic. I've heard about lease companies that charge a 20% buyout fee to own the equipment at the end, so it's an important detail to keep in mind, it could turn out to be a fistful of dollars.
I was also in favor of the credit card idea- there's a calculator here

...that suggests you could pay the credit card off in 23 months (22% APR, $2400 purchase, $130 monthly payments).
