Hi, firstly congratulations!!!

This probably is such a stupid question, but why would you need one?
Do you mean why do you need to express, or why do you need an electric pump rather than a manual pump?
Some twin mums need to express because their bubs are prem and can't suck; others need to in order to build supply, others because 1 or both twins have trouble attaching, and others because its a choice to bottle feed ebm over breastfeeding.
If you end up falling into any of the above categories, a good electric pump is invaluable - firstly it saves your hands from getting exhausted, and secondly, it saves heaps of time - doing 2 boobs at once.

Is it something I should try to find at a good price now,
Not necessarily as you may not need to express.

and if you were to buy secondhand would you have to buy new breast parts or would sterilizing be just as good?
Personally, I'd get new parts but probably sterilising is just as good.
My story:
My twins were born at 30 weeks so I had to express 7x daily to build my supply. They gradually started breast feeding at 33 weeks but still for various reasons one still hasn't got the knack of it.
At first I hired a pump for 1 month to save on costs until I knew for sure I wanted to buy one. In Adelaide the WCH hospital hires them; check your hospital. Otherwise ABA or National Pharmacies hire them. We DID have to supply our own kit regardless - so since purchasing a pump we now have 2 kits... (very worthwhile though for washing up)
I'm still expressing 6x daily, complementing their breast feeds with ebm.
All the best with it all!
