small, standalone ice cube makers
I think they call them "trays".
I knew I guy whose family had a beer tap in the kitchen from a keg in the basement.. late '50s early '60s.* According to him, this was not unusual in Milwaukee. (!?)
I started out ready to pooh-pooh this idea but I went to a site called Compact Appliance, and the device they sell does indeed look pretty.. uhm.. cool! ($239). They have reviews on the site but there is only one for this item; it is 5 stars, though.
If I were on a tight budget but just generally needed more ice than I could make/store in my regular freezer, I might check out their tiny freezer unit, which is only $89. You'd have to use trays and wait, though. If you regularly have impromptu parties where you need a lot of ice right away, I might splurge on the icemaker. In a rented apt., I wouldn't want the responsibility of retro-fitting.. what if the water line leaked or something and caused damage?
I saw a very extensive positive review of another model here
, complete with lots of pictures of the device.
