they usually retail for about £90-100 so its cheap
its an odd camera, the specs claim it can take pictures upto 1600x1200, with a 2000megapixel camera this impossible without some serious interpolation going on. so the step is to find its native resolution, thats where it doesnt do any processing on the image, since to be honest photoshop will probably do a better job than the camera does and you;ll fit more pictures in a session.
2 mega basically means there are 2000 image sensors inside the camera, but in order for it to generate 1 pixel in the image, it typically needs 3 of the cameras sensors to make 1 of the images pixels, most cameras share them , and interpolate to make it higher.
a a guess id say the 800x600 is the resolution of the camera and it doubles the size to make the bigger ones.
typically print is done at 300dpi for text and 600dpi+ for a photo printerl, this means for every inch there are 300 or 600 dots(pixels), so if your image is 800 across, at 300 pixels per inch your printerd photograph would be just over 2 inches wide, go upto a photo printer and you can see it gets small real fast.
thats where interpolation comes in, both the camera and photo printers will interpolate to make higher resolution prints, they basically examine the image pixel by pixel and insert extra ones as they go along as a very simple example say you had two squares of sold colour one red, one blue, the camera says, ok well i'll mix some of the red and some of the blue, and that resulting colour is going to be the one in the middle, this is vastly simplified, but it shows the basic idea.
things to check are the features it has how much zoom, flash etc.
the images it makes will be good for the web and lowres photos, theyll probably look just fine, it really depends on what you want to use it for and you expectations.
i believe that camera is made by samsung, it appears as different models.
but if you want to use it for anything more than casual snapshots youll grow out of it quickly
