Ive got a IBM Thinkpad T23 sat here with more less the exact same specs as as the one you just posted,
i payed 160 (2nd hand) for it about 5/6 months ago. only diff i can see is it came with a 3com wireless card
Edit: thinking about it i passed that yellow shop euro somit across from wilkinsons in sheffield town center earlier ........ (people will know which i mean
they got a Thinkpad T21 for 199
