I can buy the sony camcord if I pay the money in monthly installments.

Question

=======================================
Is the sentence above correct? Would you let me know some other expressions?

Answer 1

The only thing to is capitalize the word "Sony" as it is a proper name. Could you explain exactly what you mean by "other expressions?" Do you mean other ways to say the same thing?

Answer 2

Thank yoiu for your help.
What about the follwoing?

I can buy the sony camcord if I pay the money on monthly installment.

Answer 3

As Sra said, the word "Sony" must be capitalized. The phrase "on monthly installment" isn't correct. You could say ". . . if I pay the money on a monthly installment plan" -- or -- ". . . if I pay the money in monthly installments."
