If you can use a soldering iron, there are many companies out there that sell quality connectors ,fairly cheaply.........
I'm just about to start mocking up my system, I'll set it all up with trailing wires to check everything works before commiting to plaster and conduit in the walls, some of the cables are 'homemade', it pays to test eveything, plus some of my HDMI runs are >7m, so it'll be a good idea to check they're ok with 1080p before I can't get them out again!
Give the DIY cable a go.
Remember, heat the work, not the solder
