Pizza stones are good for baking bread on but since they are usually round it's difficult to fit a couple of wee loaves on. Lakeland now sell this rectangular stone which is working well for me.
It is not very thick so no great reservoir of heat but it is porous and so absorbs moisture from the bottom of the loaf. Also it doesn't weigh a ton!
At 41x36 cms the stone just fits my oven. Cost £15 so if it endures this is a bargain.
