I have bought a ton of stuff from them. Their prices are good shipping is quick and inexpensive. They are very responsive - even to small orders.
If you want to be totally 100% "real", you will buy fittings that are BSP (British Standard Pipe) which is what most of the originals used. That being said, you would be hard pressed to tell the difference visually between AN/JIC and BSP.
