As for refurbished models, stay away from T410 with discrete (NVIDIA) graphics. I own one and experience nothing but troubles with the thermal design. I am doing everything to keep the GPU from frying my fingers on the keyboard and/or causing emergency shutdowns - got the heatsink replaced by customer service - cleaning the fan regularly - tune software fan control, nevermind the noise - check and replace thermal grease - switch away from graphics-heavy desktop environment (Unity...) - switching off webgl support in my browser - ... Well now that I put it like this, I am thinking it might not be worth the whole effort :)
