There are two ways to choose the price of the strong single system, one is the full payment, the full payment is about 28,000 yuan, and the other is the machine supply method. The down payment is about 1 000 yuan, but the cost is relatively high. The down payment plus the final payment is about 33,000 yuan, which is equivalent to you borrowing18,000 yuan, and the interest is close to 5,000 yuan a year. So I suggest that if you have money, you can choose to pay in one lump sum or borrow money from relatives. If you don't trust his after-sales service, you can put thousands of dollars before giving it after the warranty period. I hope I can help you.
