good price - I guess my main concern would be how good unadulterated filament would be.

I know the stuff I use has been furtled with to make it better than unfurtled with raw pet or pla.

But £19 for a kg of pet - delivered, is pretty good.

But is the filament any good ?

And I'm in the 'life's too short to give a damn about recycling, I'll be long dead before it matters' camp. And no I don't owe future generations a damn thing.
Now give me an immotality serum and I'll start caring :-)
Hell guarentee I'll have decent health for a mere 200 years and I'd start caring.
But current projected lifespan is just too short to waste energy on a future I'll never see.

So I'd be buying purely on price and quality.
