I have an electric pressure cooker that has the name Technique on it and I highly recommend it. My parents bought one for themselves, loved it, and bought ones for Christmas last year for me and my two sisters. It has settings for pressure cooking, slow cooking, browning, and steaming. When the timer finishes, it moves to the warm setting so I can set it while I'm doing other things and don't have to worry if I don't get back to it immediately.
My pressure cooker requires 1.5 cups of water. When I cook meat, instead of water, I use chicken or beef broth. If I had some type of rack as an accessory, I could even bake cakes in my pressure cooker. I am looking forward to trying out a cheesecake when I get brave enough (and get around to buying a rack).
I love to cook meat in my pressure cooker because it is fall apart tender. I put an applewood rub on baby back ribs and cook them for 1/2 hour and they are perfect. I can cook several pounds of boneless, skinless chicken breasts from frozen in 45 minutes and they are SO tender.
For barbecue chicken, I pressure cook the chicken. Then, I empty the liquid and turn it to the brown setting, add barbecue sauce and cook the sauce into the chicken. It only uses one pan and I don't have to drag everything out to the grill.
My sister cooks whole chickens in hers and I made a roast last winter. My parents often make a jambalaya with shrimp, chicken, and sausage and they love it. I also made beef and potatoes last winter. I browned my chunks of beef, then I pressure cooked them for about 15 minutes until they were almost done. Then, I added the potatoes and everything finished cooking in about 7 minutes.
This summer, I cooked garden fresh green beans. I turned it on the brown setting, put in bacon and cooked it until it was almost done. Then I added some finely chopped onion and cooked until the onion was almost done. I added the required water, green beans, and salt and pepper. I pressure cooked them for 1/2 an hour and it was like they slow simmered on the stove for hours. My DH and FIL loved them.
