At my breaking point

My 8 week old used to sleep so well. The only issue is he loved being in tight quarters and never liked his pack n play for some reason. He slept just fine in his momaroo. Well now he wants to sleep in our bed next to us which I hate. It makes breast feeding easier but it's dangerous to me and lately he's been asking up every hour to feed instead of going his usual 2-3 hours. I am about to break down and buy a damn dock a tot just for him to sleep safely. Has anyone used one and is it actually worth the money? I hear all of these moms saying yes but I just wanted to know. My luck my son would hate it.
