Honestly I usually use paper-towels because I'm cheap, and I don't drink coffee, and I'm experienced enough to check germinating seeds often and pot them as soon as roots form. I know a lot of people that let their seeds get tangled in the paper towel (its not a difficult thing to do especially with tomatoes, just difficult to untangle and pull apart).
I usually plant sprouts into cells(usually 72cells/tray) but you could use any small pot or growbag.
