In terms of longer focal length, I have the DA*300 and it is dreamy - and so is the DA*200! I believe the 60-250 is too. The big sigmas are good value I think although they are big lumps to carry around so that's worth consideration. I rather like the sigma 70-200 f2.8, which you could use with teleconverters (1.4x or 2x) to modify the focal lengths and still get decent results. Definitely worth a look, although I don't think the sigma TCs yet support HSM focussing, which the lens has...
Of course the pentax 55-300 is also worth a look. Very good quality for the money and great value. Would leave enough change for all sorts of other things too
Decisions decisions...

Others here will know whether there are other brands of TC which work with HSM. I am fairly sure that Sigma TCs will only fit Sigma lenses, but I am unsure whether other brand TCs will also fit Sigma lenses...
Hope that helps

Looking out the window tonight I reckon it'll be a while before I see the moon again!
Cheers

This was taken with the sigma 100-300 (@300) with 2x teleconverter on a (now evidently slightly wobbly) tripod (I fear I need something a little sturdier than I currently have for a 600mm lens:shock, and then a little PP.

Hope you like it. I have a number of moon 'variations' on flickr... some of them even look a little more normal.

Alternatively you could look at a 'true' macro lens, they will tend to be 'faster' I think and have the 1:1 potential - the DFA100 is great, as is the DA35 (I have both and love them). and there are offerings to be had at 50mm, 70mm, 90mm, 105mm and longer if you are prepared to hunt around on ebay
Finally, you could try using an extension tube with your current lens. If you have a manual aperture ring then this might be a very cheap option ('dumb' extension tubes can be picked up for a fiver or so I think)... if you need to control the aperture from the body then you would need a tube with the relevant contacts, which are harder to find and more expensive
