teleprompter application in vb.net

Question

Dear All,

              I am developing a windows application for tele-prompter in vb.net 2010.
Tele-prompter required large quanity of data to scroll and in vb.net we have
certain limitations in the nummber of character hold in controls like richtextbox etc..
. We need the font size as 72 size letter .So kindly suggest the best control which can used for scrilling the
text .Also if any of them having the pre experience in such development please share with me the sample
 codes and controls which use them for the code part.
