New slow cooker?

[momb]

Please recommend a slow cooker to me. I have a standard Morphy Richards stainless steel largish one and use it a lot.
What I'd like a one which works as well as the MR but the inner and lid could go in the oven (all the ones I've seen have glass and plastic lids) or could go on the hob. So basically a combi SC/casserole dish.
Thanks in advance.
