Thanks for the replies.  I think i will go ahead and buy the smaller fuel bottle and try out the stove.  The one tha i got is the Primus Multifuel.  Does anyone have any experience with this particular stove?  i tried to take it apart to familiarize myself with it.  I was unable to unscrew the bottom of the stove with the two small holes.  Also, the service tool they included doesn't work that well with the jet.  I think i'll try to get a socket wrench and try to remove the jet.
