just buy any1 from hardware shop. I bought from a very old shop, cost around S$14. Its a breeze to cut PVC and those rubberhose. U will appreciate how conveinet it is and how clean the cut is. Sawing PVC is another way, but imagine u got so many to cut and re-cut. Nightmare.
And as for glue, just ask them for PVC glue. The can, they show u will indicate PVC glue on them.
