With all of the good advice you've received, it sounds like you've already decided - but I thought I'd add a comment about the quoted statement above. While most pns cameras will allow close-ups, the quality of the images varies widely between cameras and even between images taken on the same unit. All of the pics that I've posted over the past several years have been from a few types of pns cameras. While some of the shots border on acceptable, the amount of effort, time & frustration that it took to get borderline shots is huge. These little guys sacrifice any control (like specific focus point or depth of field settings) that are really critical to good compositions. Focus stacking (details elsewhere) is also not an option.If you just want "closeup" photos (which a lot of people call macro photos), a lot of PnS (Point n' Shoot) cameras will do you just fine for between $200-$400, depending on how nice a camera you want.
If you'rre comitted to getting a PnS, check out the Panasonic Lumix line. Last year, I wanted a small lightweight camera that I could easily take hiking / biking and not worry excessively if it got trashed (so I wouldn't risk my more expensive Olympus Stylus). My wife picked up a Lumix DMC-F2 for under $100 iirc. Even though it is 1/2 the size of the Olympus, it does everything better (by a lot).I would like to keep it under $400, a nice PnS would do fine for me.
