I second what Squishy says. I used to use exactly the same combination of Fuji S9600 and Raynox DCR-250. The Fuji's screen flips out which is useful for low down macro shots. Just by itself, that camera is good for macros. You might get it second hand for around £200. Not the smallest camera ever, but that does actually make it easier to handle for those tricky shots.
Buying second hand from reputable camera shops is a good idea - less risk than eBay, but much cheaper than buying new (useful list of shops here -
