Tan - you can get those mesh feeders from places like target, they are a tommee tippee brand. I'm thinking of getting one soon too!!
I'm an MCN convert too!!! They are great! I started of by using disposables, then went to terry and flannelette flats, and now use MCN's. I have about 10 peapods. They are ok, am looking at getting some hautes. At the moment I'm still using sposies at night time, but I have just bought some green kids dreamy night ones, plus a couple of bamboo flats to use as inserts. Ethyn is a fairly big wetter so its just trial and error for us at the moment with them.
