Kodak P850 if you can get one is really nice. I got one for my mom last christmas and it was like $450 at the time, but now you can get em off ebay for around 220. THat may be a lil out of your range, but you can check the lower lines under it. They have sum nice features, not sure wat all, but the pictures are really clear and come out great. It even has a glare thing, so that you can take pics looking straight into the sun and it comes out perfect.
i sell camera at sears so I know a fair amount about them. Are you looking to spend 150 on ebay or at a retail store because there is a huge difference in selection. If its on ebay i would say look at the sony dsc-w50 or a canon sd400-sd450. There all great cameras and around 150 on ebay. If your looking to buy it at a retail store theres not alot of options at that range for aquality camera but id say go with a kodak or fujifilm then.
