There are many styles of dry erase boards for you to choose from, so finding the perfect match for your conference room needs should be relatively easy.  There are also a large selection of dry erase marker colors available to fit your needs.  The boards come in sizes ranging from laptop size to the size of a high school chalkboard.  Once you determine what size you want, you should be able to order it via a local office supply store or catalog company.  Being able to write down points during a conference and change these points, or add to them at will, will surely benefit your meetings greatly.
