I love, love, love our video baby monitor! It's the best for seeing what he's doing in bed. Especially now that he's bigger and I can have a quick look to see if I need to go in and lay him back down etc. well worth the money IMO.
And as for carriers, I have a version of a hug a bub which was awesome when he was little and I use a manduca now. I did have a mini monkey on loan for a while, but neither of us liked it. I highly recommend checking out Facebook for a local baby wearing group, they usually have librarys of carriers so you can test a few out before you purchase one
