Yeah a quick look at current UK mobo prices also reflects the same type of decrease in cost of the nForce2 based mobos.
www.dabs.com shows:
SiS746FX £50
KT400 £62.50
nF2 £78
nF2 NF7-S (ie full nF2 implimentation) £99

I don't think there's a doubt nF2 is superior and certainly generally less problematic than either the SiS or VIA based alternatives. Although without it's great onboard goodies basicly all you have is a few % more perf than the competition, even when using DC-DDR. Is that worth an extra £22 (NF7 type) or £43 (NF7-S type) over the competition ... or to put it another way is it worth paying an extra 40% (NF7 type) or 77% (NF7-S type) on the price of the mobo? IMHO that depends upon your budget, prefs and reqs. The extra £33 (the average) is enough to...
1. Double your DDR RAM to 512MB and with a good brand like Crucial.
2. Get the Rad9700 instead of Rad9500PRO.
3. Get the Rad9500PRO instead of GF4TI4200.
4. Add a CDRW or DVDROM drive to your PC.
5. Add a basic USB scanner to your PC.
6. Add a 120GB HD instead of a 60GB HD.
7. Add a basic TVcard to your PC.
8. Buy a great HSF in order to maximise the potential of your CPU (etc).
9. Add a decent soundcard to your PC.
10. Enable you to get a faster or better o/c'ing CPU.
11. Buy 1 set of Lexmark injet ink carts (LOL!).
