An alternative to a Neti Pot is the Grossan Irrigator. It's a tip attached to a waterpik, and my sinus doc likes it because the high volume of water makes sure you don't dry out, as well as cleaning you out.

I use it with salt and sometimes a eucalyptus product, and it's terrific. Here's a link to a video of it.
