Yes, there are suppliers besides Moss. Moss skates along as the default option for LBC parts, when there are other suppliers around, most of whom are far better. The Roadster Factory and BP Northwest are two. Rimmer Bros in the UK is another, also Revington TR in the UK. If you must go to Moss, you can get their parts through a distributor like the Little British Car Co. for about 5% less, although delivery will be longer. There are a number of minor suppliers, too, which you can find through an internet search, but they don't have the broad parts coverage of Moss and Rimmer.
