These guys
https://www.siliconehose.com/ make really, really good stuff. I was waylaid a couple of years back after a 1/4" coolant line on my 95 SR cracked behind one of the cam gear covers, as they're all-but-inaccessible unless you're doing a timing belt job. I asked Josh what a source was for the BEST hose I could get so I'd never have the problem again, and he suggested this company. I was sold after I got some of the product in my hands.
For my SR, and for my latest one, I order 2' of 1/4", 3' of 3/8" (throttle body) and 5' of 5/8" (heater hose). It's super flexible, resistant to kinking and is really thick-walled, too. For the snazzy-inclined, you can get blue instead of black, but don't do it just because I do. It just looks good, I think.
I just ordered some more and saw they have free shipping on orders over $35 (last time their shipping was pretty pricey, for whatever reason) for a 'limited time.' Anyway, I suggest them.
