I would *strongly* recommend you NOT getting a salt system, yet, for 3 reasons:

1. You need to learn to operate the pool without it -- we see people all the time in pool trouble, because they can't do so.
2. You need to hold off adding salt to your water, till you've seen the condition of the pool. If corrosion is beginning, you don't want to accelerate it with salt.
3. You'll have a MUCH clearer idea of what you want and need, after you've run the pool without salt, this summer.
