Hi Jon, if you haven't made your suit, here's a place that makes them for less than $500.
Spring Checker
Blk 1004, #05-04, Toa Payoh North, S(318995)

Apparently, the company is a wholesaler to departmental stores in Taiwan/Japan(?). If you aren't too tall, getting a suit off the rack there will cost you a lot less than having it custom made for you. He's got a wide variety of fabrics and cost at least 30-40% less than what you'd be paying for at Far East /Peninsula/Lucky Plaza.....it's the location, mate! Btw, Spring checker's located in a factory so don't be shocked by its surroundings. The range & service is every inch as good if not better than those sleek-talkers in Far East Plaza

and did I mention that the prices are fixed?
