D70S is the norm nowadays. slghtly larger LCD screen and a remote lead connector, as opposed to a wireless/IR one on the D70.
Give it a few weeks - the D200 that I referred to in the earlier post is going to be actually on th emarket in the next two to three weeks and alot of D70 owners will upgrade. Prices will reduce - trust me :-) a 30 second hunt on Google has found one at £486, though it doesn't make clear which lens is bundled.

PS the 28-70 isn't bad a all but the 18-70 is a corker of a lens.
