If cost is an issue, you might want to consider a below ground pool with a liner rather than a gunite pool. Add a spa, decking, and high end equipment and you can easily be up in the $40,000 to $50,000 range, depending on size. Talk to a few pool owners and pool builders in your area for more detailed information.
One and a half hours is much too long to cook the chicken at 350 degrees F. The time your chicken will bake in the oven does depend on the internal temperature and the size of your chicken or chicken pieces. Generally I bake chicken at 350 degrees F. for 30 to 40 minutes.
You can cook it at 350 degree. If you set the oven at 350 degree, then you will be required to cook the chicken for 35 to 40 minutes. But if you preheat the over at 450 degree, then not more than 15 minutes. But still, its not all about temperature. There are lots of others factors need to be considered when you are cooking chicken.
