Let's start at the bottom, or rather the bases. Here are some excellent scenic bits that could be used on unit filler bases, on terrain pieces, or as decorative bases for a single figure painting project. These dwarf bits from Scibor miniatures are really tempting, I would love to integrate these into my dwarf army.
More dwarf goodness from Black Scorpion miniatures, of the "fantasy football " variety. They have a good selection of pirate skirmish figures too, these are just a couple of examples from that range.
Perry Miniatures have finally released plastic mounted men at arms for medieval forces, though Warhammer Empire players might be interested too.
Another company well worth checking out is Historic Art miniatures. As well as a very fine range of historical figures, they produce some excellent fantasy figures, such as this Alice and Merlin.
Here's another wizard that would grace any glass cabinet, a Gandalf from Knight Models.
Finally, an absolutely beautiful piece of terrain, a blacksmith's forge from Tabletop World. If you have never visited their website, click the link and prepare to be amazed!
