If you want high quality at low price then I'd suggest these:

I agree with all the reviews on the
Wiggle website - they are exceptionally capable tryes.
I've used them for a few thousand miles in 700 x 28mm and 32mm on a touring bike. They have low rolling resistance (they have quite a narrow profile - tall rather than wide - so not too much rubber contacting the road), great road 'feel' over a largish pressure range, don't suffer much from punctures, steer very precisely and they feel robust so they're happy with heavy loading. They can't grip as well as a tyre with deep treads (= high rolling resistance) but they're not bad either. One point that I don't see mentioned much but it's important to me - the Randonneurs centre brilliantly on the rim so a very balanced tyre resulting in a completely smooth ride. Only downside - they're not easy to fit or remove as they're tight on the rim (which probably explains their well-balanced nature).
Out of curiosity, I changed over to Schwable Marathon Plus. Didn't take long to realise they clearly have higher rolling resistance and feel 'dead' at all pressures - not nice. And they've worn more than I would have expected. And they were even harder to fit than the Randonneurs. More expensive too.
