I've used those QT102's before (and QT150, which is a 5 channel version). They work pretty well, but they aren't as cheap as using a 16F727 and it adds more parts to your circuit.

You might want to check the Atmel website... I think the QT102 has been superseded by a newer part and isn't recommended for "new designs".
Maybe I'm wrong...
