brew hardware is def the place to buy camlocks. they also sell high quality silicone hose which is what you want.
i started with the stainless quick disconnects from morebeer. super nice pieces of equipment buy holy cow expensive. as you develop your brewkit - who knows what connects you will need. camlocks work great and are much more affordable. you'll be glad you went this route down the road unless youre rich.
get yourself out a notepad and sketch our your brew system. sketch in the all the kettles, pumps etc so you can gain inventory of how many male, female, elbows etc of what you will need to order.
