Could I collect Romans ?

Like so many I find much of my inspiration for new gaming ideas, periods and genres from books. A couple of Wargames Illustrated magazines ago they did an article about Romans and mentioned the Simon Scarrow series about Cato and Macro. Since then I have picked up some copies in charity shops and have been really enjoying them. But not sure I need another army to collect just at the moment. Perhaps one day I can get some of those lovely new Victrix Romans.
