After a few punctures on my GP2000s (why so many broken bottles?) its about time to replace, however my pocket is feeling a bit light at the moment. You can get Continental Ultra Sport II for £13.99 on Wiggle, whilst GPs can vary wildly, but a pair might typically be north of £50. Those of you that have gone 'downmarket' in the past, can you feel the difference? Is it 'all about the tyres' or don't you care if you have strong legs?
