I bought a Thinkpad X200 fully loaded with a Core2Duo 2.4ghz, 4gb ram, ultrabase with the DVD burner and pretty much every option possible (bluetooth, webcam, turbo cache, CDMA mobile card) for less than $350. I would consider it a very nice upgrade from an T41, I used to have one of those, it is just as solidly built and has the awesome Thinkpad keyboard.
The X series is right up there with the T series on build quality, it is just a little smaller. Acers, Compaqs, HPs and pretty much anything consumer level feels like a cheap toy compared to a Thinkpad, $300 might get you a faster processor, more RAM and a bigger hard drive when buying cheaper laptops, but you don't get the build quality.
