What are some good desktop tv tuners and capture cards?

Im not going to be buying them anytime really soon but i need to know what to look for in tv tuners and capture cards for my desktop, idk which is better PCI, PCIe or PCI 2.0x16 or whatever, the motherboard im getting supports all of them. i need to know what a good price is and what determines the quality as i have never bought any expansions like those, only sound and graphics cards. i want to be able to put in cable and or phono cables and be able to record tv and/or xbox and stuff with sound. thank you for any help. please provide links if possible.
