Bed side bassinet sleepers?

I’m wanting to start to buy my baby’s furniture I was looking at the “baby delight beside me” bassinet is it good?

I’m looking at buying it secondhand because there’s a ton being resold on my market place for less then half the retail cost. If it’s not good or if I shouldn’t buy it secondhand should I just jump to buying them a crib? I just got into my second trimester and I think it’s safe to start purchasing baby stuff. With that being said what are some must have items for a new mom?
