Those ikea ones are awesome. they are expandable and work like modules. they are great.
my advice for budding wine (and beer) makers is that you cannot sterilize enough...but for pete's sake make sure that you remove all of the sterilant when it comes time to use the sterilized item.

in my experience...home made wine and beer gets markedly better with just a wee bit of aging.
i guess it all depends upon how desperate you are!
but i really like the idea!
