Which camera to buy Nikon d80 with 18-135mm lens. Or Pentax k200d with 15mm-55 lens (II)?

Hi

I can't make my mind up. Both cams are on sale at the same price £340 (Both look a steal).. Both have great reviews. Nikon 80 is older but has a solid consumer base. Pentax 200 has newer features. Help!!

Thanks Sab
Update: Sorry Pentax lens is 18-55 mark 2, not as in title.
