TV Tuners are tough to come by in laptops I believe. The only ones I've seen with them are the Toshiba Qosmio line and they are expensive and bulky.
I like ABS a lot now, I'd recommend checking them out both on their site and on Newegg's. I'd also recommend buying an after-market tv tuner, they are generally of better quality and I've seen some no much bigger than a usb flash drive.
