Honestly each to there own, considering you can buy ss braided hose from summit cheaper per meter than rubber hose locally, and once you add up brass fittings and good quality hose clamps, the price really isnt that different. Yes some of the bended fittings are a bit pricey, think the most expensive one on my car was like $30, but most are between $6 and $10, comparatively Norma stainless hose clamp = 2.50 and brass fitting = ~ $6-10.
Main benefits of the flash wanker stuff is when you need to remove a hose, instead of fighting and swearing for 20 minutes trying to get it off then ending up slitting it with a razor blade, thus making it to short to re use and having to go buy more ludicrously expensive hose from the auto shop to replace it you just pull out your equally wanky anodized aluminium spanners, give it a quick flick of the wrist then pull it off....Put one of your flash wank factor plastic an bungs in the hose, a flash wank factor plastic an cap over the fitting (both stupidly cheap) then you can go drink beer.
Cheers.
