I've used mdf cut to size for pieces of unusual thickness where I don't want to handle a full sheet. Very good service and the accuracy is fantastic. Delivery always factors into small quantities though. Builders yards are usually only £1.50 or so a cut, you have to keep a careful eye on them and don't forget that the outside edge of the board is best out of sight or trimmed off, avoid using it for facing edges.
