The new price list is here a couple months early. The increase is about 9%, so on a $550 reg, it would be about a $50.00 increase. On a $250 Mk 2 R190, the increase is only going to hurt half as much.
The early release of the new catalog and price list was apparently done to get both the new catalog and new price list out before the DEMA show.
As for the reason for the price increase, I supsect it has nothing to do with the price of oil and everything to do with the devaluation of the dollar. Much of the scuba equipment sold in the USA is made in foreign countries and a falling dollar means increased costs to buy foreign goods. When you consider how much the dollar has fallen relative to other currencies over the last year or so, a 9% increase is really nothing to complain about.
