If that's your only reason for wanting/needing a chamber sealer, you're missing out.
There are various methods for sealing liquids inside a bag without a chamber sealer: freezing the liquids before adding; using a gelling agent; the double-bag method; the Archimedes principle method; hanging the bag off the counter; using a handheld sealer, being bloody careful what you're doing, etc.
Naturally, some work better than others, but for home use it's perfectly simple to get along without a chamber sealer. Hell, I know a few restaurants that manage okay without one, although they do use a moderately expensive external suction (*snigger*) model.
That's very pleasing to hear. May I enquire as to what you were doing pre-Masterchef and what you find yourself doing now?
I hadn't thought of freezing - blimey that's a bit obvious! To be honest I haven't looked into it that much lately as i'm waiting to buy a house to fit out a kitchen properly and that probably won't be for a year or so
