i think that's the newish, non-knurled newton 600. he's looking for this one, which went for around $122 on ebay yesterday:

i've posted here previously about the old-style 600, which some of us in the philippines have found, NOS, for as low as $14 (i kid you not! that was another FPN friend who snagged that, black with a gold B nib, no less; i got a few for $31 each--one of which, a black F, i'm trading away for that black B ). the local importer of rotrings, parkrs, and watermans was clearing out inventory. not surprisingly, the supplies didn't last very long (and no, sorry, i have none for sale--am holding on to the three 600s i got, knowing i'll never find them at this price again.) this was a happy fluke, but i'd think that any old-style 600 in the range of $100 would be a bargain. here's a pic of two of those i got:
