I got an Actifry in the product test Mumsnet did a couple of months back. We use it at least three times a week, if not more now - it's particularly great for quick dinners for DH and I in the week.
I'd never in a million years have spent £100+ on one before I'd tried it. Now I'd definitely replace if it died (although I'd shop around on deals - the one they sent us was £279 RRP, but I know someone who's just bought it on a deal with a bundle of bits for £170).
