I assume when you say comparable, you are thinking granite-like? Like some of the engineered substances? At this thread:http://messageboards.ivillage.com/iv-hgfirsthome/message.asp?webtag=iv-hgfirsthome&msg=2852.2
there is a comparison of different countertop materials and this source says that engineered stones are roughly half the price of granite
and this resource:http://www.kitchenbathideas.com/product/countertops/countertopschart.html?sssdmh=dm17.308320&esrc=nwkbi41
directly compares a number of countertop materials for maintenance issues, DIY-friendliness and cost.
Hope this helps... Please let us know if there's more we can answer for you!
