I'd disagree, you do if you know what you're letting yourself in for (remember to read the T&Cs etc) and you get a very cheap flight. You're only on it for an hour in most cases so the quality of the ride isn't all that important. Just make sure you have insurance in the event of a cancellation stranding you.

Don't assume you're getting full service, but then for 25 quid return including taxes (which is what my trip to Hamburg cost two weekends ago) what, to be fair, do you expect? (I wouldn't pay them several hundred quid for a short-notice flight - that's what the full service airlines are for).
