Shelley - Good choice. When I was choosing which to buy, I specifically wanted a stainless steel pot, as opposed to a non-stick one and the IP was about the only one I could find with that. They do a non-stick inner pot too, as an accessory.
If there are ever any issues with your IP, their service is excellent. There is a closed UK group of IP users and I learned a HUGE amount on there. Several of us arer on there, although bearing in mind the IP uses our real names, we're all still incognito.

If you ever want the group details, any of us potters can direct you there.
My only comment would be DO NOT have a dickie fit when you see the size of the packaging the pot comes in. It's a BIG box!
My OH is away for a golfing competition for the next couple of days, so I a, singleton cooking. We had a scrumptious brunch before he left, si I just wanted some soup this evening.
I had some leftover butternut squash soup in the freezer from last week, but it didn't look quite enough, so I put about a cup of water into the pot, and added the frozen block of soup, and a few cauli florets. I gave it 5 minutes pressure cooking, then blitzed down the cauli and added some soured cream just before eating. I'm very, very full!
I must say, my stick blender is coming into its own with the pot for soup, when I want it less chunky.
