I want to say that $2000 for a T370P is FAR too much. You would be paying several hundred dollars more than it is really worth. For that price, you would be much better off getting a newer model. Which place is selling it for that price?
On Ebay, search for item number 140069824197 and you will see a current auction running for a T350P for $1125, much cheaper than the $2000 for the T370P you say and the only difference is this has half the memory but it can be bought for relatively cheap.
I have an older model TX790P and an issue I have with it is that no matter what I do, the fan turns on a few minutes after the laptop is powered on and keeps running constantly and never ever turns off. Otherwise, no complaints really.
The TX790P is essentially the North American model of the TX27GP you are looking at.
May I ask why you are looking at a North American T model and a European TX model? I assume you live in India perhaps?
