As of this week:
Lesser 13 oz - ~1860 for a 2-piece suit, ~1280 for a jacket only
Smith's Steadfast (14-15 oz) - ~$1750 for a 2-piece suit, ~1200 for a jacket only
Harrison's Oyster (13 oz) - ~$1550 for a 2-piece suit, ~1100 for a jacket
Harrisons/P&H/Hardy tweed lines are all in the 1100-1200 range for a jacket. Scabal 100% cotton was in the same range. Scabal cotton/cashmere is closer to 1600.
A year ago, Lesser 13 oz was $1650, so it's increased 11%, though I think the price had remained constant for a while before July 2010.
Maybe I am imagining things, but it seems to me that trousers have increased in price faster than jackets. About 30% of the suit price is for the trousers. You can save considerable money by doing local CMT for the trousers (I will be saving $300-400 on a Lesser 13 oz suit by this method).
