In customer/main/products_t.tpl, change this:

{$lng.lbl_our_price}: 

To this....

{if $products[product].is_variant eq Y}{$lng.lbl_priced_from}{else}{$lng.lbl_our_price}{/if}: 

Also, create the new langauge entry under Labels called lbl_priced_from and use whatever text you want, such as "Priced from" or "Starting at", or you could just enter the text in the template if you aren't using multiple languages.
