I used an outside vendor with the narrowest paper available (24"). $3.50 per linear ft. I was satisfied with the results. In the end though, I would not do it again because it was quite frankly too large to be displayed at once. it was approximately 65' long and the facility we held our reunion did not allow items to be placed on the wall. i ended up having to setup about 70' of tablespace to display it. at that length the printout was over $225 dollars so it must be part of your reunion budget. I have done another one for another reunion that I used 12" paper and i was able to display it on a table half the length by placing half the chart on one side of the table and half on the other. that worked well.
