Wacom Tablets Users - Question

[RGD.]

I'm looking to get a Wacom Tablet, specifically either the Wacom Intuos4 Small or the Wacom Bamboo Capture. The Intuos4 is twice the cost of the Capture with a smaller active area. I'm not looking to spend anymore than needed - but I don't want to have to buy something again in a year or so.

I am not an artist. There will be no free hand sketches, drawings etc being done. I am simply looking to use the tablet for photo editing in Lightroom3, PS and Elements. That's it. The pen being more precise than the mouse.

The Intuos4 medium is a bit more than I want to spend so the question is - is the small large enough to do just photo editing. And will the Capture perform well enough for the same editing.

Thanks,

Ron
