Dear Shuie,I'm sorry to hear that you had a deflation of your saline implant. However, this is a occurs very often. In my opinion, the best option would be to replace them both with silicone implants. Silicone implants are less likely to rupture, feel and look more natural but, they are a little bit more expensive. On the other hand, having multiple surgeries to replace deflated saline implants may be more expensive in the long run. I hardly ever use saline implants now a days as most patients places in the US prefer silicone. Prices range from practice to practice, depending on the surgeon and location. Many surgeons offer free consultations, so the best thing to do is make an appointment with your plastic surgeon so they can explain what your options are, the risks and benefits with regards to each, and the cost. Hope this helps and best of luck.
