LTB: T520 or W520 with 1920 x 1080 (WUXGA TFT)

[garnet]

After much thinking I am not sure I want to go for a TP with island style keyboard.

Hence looking for a T520, as the last having proper tp keyboard.

I am looking with something with the following as minimum

i5
nvidia graphics
1920x1080 creen
4 GB RAM
HDD doesnt matter


Price is negotiable for me.

questions here:
It is worth it getting one of those?
Where can I find one (I am in UK ebay USA is not a good option)
Do you have one you want to sell? If so, PM me, please.
Any suggestions are welcome.


EDIT: W520 also in the wish list.
