They all sound a bit expensive to me, but then I always did go for the absolute bargain options. The second one reminds me of the one we had many years ago (and yes we probably paid the equivalent of at least that much, but it didn't seem so much at the time<g>).
Not sure about letting hens out 'in the evening' other than high summer. If they can't be out while everyone is at work, probably better to use the 'hanging cabbage' option, move the house fairly often, and only actually let them out weekends, or for half-hour or so before a 'last feed' (and get them used to the 'last feed' before letting them wander).
