Money Field

Hi, i want to create a money/currency field but get confused on what the
right approach.

I've been looking at custom validator, translator, mixin, even extending
tapestry TextField it self.

Basically the requirements is:
- When the user type 100000, it will be shown as a certain format (ex:
100.000)
- There's a possibility/optional parameter that you can show the currency
symbol ($100.000)

Can anyone give a little bit direction? Thanks
