sounds like the price is staying the same
"For 2006, we will begin switching to Tange Prestige CrMo. Tange Prestige does not have the thermophilic properties of Reynolds 631, but overall its tubes are stronger – thanks to Tange's heat-treatment process. Old farts need no explaination of how nice Tange Prestige is; for the youngins' let say it is in the same league as Reynolds 725. In all respects, this is an upgrade, but we will be keeping the price almost the same as 2004 and 2005, because we all know how you feel about a good deal. "
