Wachovia has a credit card with a very low interest rate for small business. I used it my self to purchase a Ditch Witch 410. Interest rate was a low 1.9% in August. Discover Card will also give you a low interest rate for major purchases. Just make sure you get it paid off in a year so it will be tax deductible the same year you made your purchase.
