tempted by the Sandstone fireplaces

HI

Great site.   I am remodeling and (http://maplered.com) am so very tempted by the Sand (http://maplered.com) Stone (http://g603.net) fireplaces sold under the name Tulikivi.  I keep seeing information indicating the sand (http://maplered.com) Stone (http://g603.net) will stain however the Tulikivi & local sites indicate the Stone (http://g603.net) doesn’t stain.  Am I confused or are the different stand (http://maplered.com) Stone (http://g603.net) quarries different?  Any idea how I can research the different sand (http://maplered.com) Stone (http://g603.net) s to compare (Finland (http://maplered.com) , Colorado)?

Also, does anyone have a list of things I need to consider before purchasing a sand (http://maplered.com) Stone (http://g603.net) fireplace?  Any place I can go to search for long range problems?

THANKS

KC
