Self-Made
The certainly look easy enough to make. Our used C-30 came with a home-made lazy jack system essentially as follows: There's a line running down on each side of the mast from the spreader socket; at the end of each line is a nylon ring (most systems use a block here). From the ring, the free end of the line is then tied off to the aft lower shoud (to help hold the lazy jacks away from the sail/boom). Then, beginning at the aft end of the boom on the starboard side there's a line that runs up to the starboard ring, down to the boom and through the base of a cleat on the underside of the boom; up to the port ring, then aft to a cheek block on the aft port boom and then to a jam cleat. This system works quite well for our needs and would seem to involve only the cost of the line, the rings (or blocks) and the cheek block/cam cleat. One advantage to this setup is that once the sail is furled you can slack off the single line attached to the boom, and run the lazy jacks forward to the mast -- out of the way, and no need to modify your mainsail cover to accomodate the lazy jacks. I'm sure there are many other configurations but the answer to your basic question is that, yes, you can make a system yourself, at I suspect less expense than a purchased system. Good luck!
