We have used this guy. The only thing which I didn't like was the mince. Doesn't look real nice or smell real nice. The girls wouldn't touch the chicken mince, if they did have a bit they threw it up. The beef mince was a bit better and they will eat it, but they aren't happy about it.
The chicken necks and carcasses, bones and lamb flaps were good. I'm getting a delivery of these soon. Cheaper than the shops. Only thing is they come in a 10kg bag, so you have to seperate them, but I use all those plastic shopping bags you accumulate.
