If you can wait until January/February to buy the new liner, the places (at least down here) often offer really good discounts on"last year's models" because the new liner patterns are published around March. I don't know if it's possible to install one in January in your climate, but you might could at least get the contract signed and get on the list for when the weather warms up--and save yourself some money that way. My new (discounted model) liner cost around $3K a couple of years ago, installed.
