How to customize ProductListControl and/or ProductListItem cl*****

I'm working with the CS2002 SP3/FP1 StarterSite - trying to use it as a
basis 
for our site.  I want to change how products are displayed from the layout

used in the Starter Site, but the controls used are in an assembly - it
looks 
like it uses cl***** "ProductListControl" and "ProductListItem".  I don't
see 
any method (other than using the stylesheet) to customize the output these

cl***** produce.
(ProductListItem is sealed, so I can't inherit from it to extend/modify
it)

Surely there is a method I'm not seeing?  Do I need to totally rewrite
those 
components on my own?  If I do that I suspect I"m going to be missing some

events and interactions the rest of the site is expecting from those 
pre-built components.

Thanks
