Lightweight ComboBox for Action Script 3

I'm looking for a lightweight ComboBox for as3. The normal ComboBox component introduces an overhead of 60kb, that's too much for a banner or a landing page. I google this looking fo开发者_StackOverflow社区r options but what I found are paid custom components. Do you know where I can find a lightweight combobox for as3?

Thanks in advance, Jonathan.

Here is an open source component that is suppose to be lighter than the stock ones: http://www.bytearray.org/?p=137
