I just got my Kodak E6 minilab chemicals (fixer and colour dev replenisher and colour dev starter) from Vanbar.
If you want bang for buck, I would recommend mixing your own bleach (vanbar has all you need in raw components) or getting Agfa bleach from Vanbar, Kodak E6 fixer ($13.70 approx), and Fuji E6 Colour Developer Replenisher which makes 235 or so litres (ill be going Fuji next time) - mix the starter yourself, its only 2 components, if youre into it I'll look it up for you.
And mix your own first developer, save a shit tonne
Ive used the Tetenal C41 kit before @ 31c (easy to stabilise temp - actually no need to, it doesnt drop during summer with the short processing times

) with excellent results - actually better than any lab I've had 120 C41 processed at - theirs have thin range compared to tetenal negs - also no roller scratches.
Hell, you can make a good first developer from paracetamol (the cheapest stuff you can find), sodium sulphite (made from sodium metabisulphite which is sold in the wine/beer making section of a super market for $4 for 250 grams) and sodium hydroxide (caustic soda, $5 for 500 grams of 98%) <-- I've made it a few times, let me know if you need help there too
