serious: Thanks for responding. You listed out some real possibilities for this show imo and, if any or all happen, could explain the smiles and enthusiasm conveyed to you at the other show. I guess we'll have to wait and see. The booth setup at Vegas does look very impressive (thanks Testsite1) but it would be nice for there to be more reasons than that for them encouraging you to go - 'and you won't regret it'. Again, thanks for your time and willingness to share. Bill
