Just looked through the way back machine and back in the day the Abit NF7-S v2.0 one of the best boards of it's time cost - £67 inc VAT
And the most expensive, top of the range motherboard for either AMD or intel back then was £140...about the price of standard base models now!
To be fair I seem to remember every motherboard I've ever had costing more than £100 except the NF7 - so thats KT7, KT7A, KR7A-RAID, DFI Ultra-D, IP35 Pro..
