We have both a RnP and a PnP, plus a swing. We need all 3 cuz we have multiple levels in our house. DS sleeps in our bedroom - starts off in the RnP then we switch him over to the crib after his MOTN feeds. We love the RnP b/c he is very fussy at bedtime and won't sleep in the crib.
Our PnP is in the living room (2 floors down), and it has a changing station and a newborn napper. We use both features right now as I don't want to carry DS up 2 flights of stairs to change him every time. The napper is contoured and he likes it; however some days he hates the napper and will only sleep in the Swing! All 3 of these I got < 1/2 price off Craigslist.
I much prefer My Brest Friend pillow over the Boppy, FWIW. Other things that have been invaluable so far (DS is 3.5 wks old) are:
changing pad cover, mattress protector, tons of burp cloths (we use toddler-sized cloth diapers for that), activity gym, wash cloths and baby soap/shampoo (for baths), hooded towels, nipple cream, nursing cover.
