definitely love the Ecover tablets here too.
i tried doing the diluted vinegar thing for a while and i just can't stand the smell. i can smell it through EO's and it bugs me.
so what i use is Citrasolv. i buy a bottle of the concentrated stuff about 1x a year. it's heavily concentrated so you really only need a tiny bit. it cleans everything really well, even gets rid of my hard water stains in the toilet and shower. and it smells divine. i use it for cleaning everything pretty much, including the floors (though i don't think i'd use it on wood floors regularly, seems like the citrus might damage the wood? i dunno). i buy it through a Frontier coop, but i've seen it at a number of grocery stores that have an organic section. just make sure and get the concentrate not the spray so you don't have much in the way of packaging to deal with.
for laundry we use Charlie's Soap. i love it. it cleans really well, our clothes are so soft, a small little package lasts for over 2 months (even with laundry for 5 people and diapers). even if you pay retail it's cheap, and i get mine through a coop and it's about half the price of retail. i also adore that it comes in a little brown paper sack - it used to drive me crazy that i had to recycle a big plastic container on a regular basis, and i couldn't find any eco-friendly laundry detergent before that in anything but plastic.
