Bad news all round, hope your Son is on the improve.
First minor question did you keep a grinder?
If you dont like plunger then avoid a mesh based drip filter for a start as they can be a little muddy like plunger depending on technique. Personally I dont like paper filters either but a really simple solution is this one below the Neru Sock or more options here http://sorrentinacoffee.myshopify.com/ and a simple stovetop like the Bellman with the milk steamer might get you back and caffinated :)
