I just thought I'd post this link:
Playing with Plastic Orcs
em4 makes some incredibly affordable plastic minis that are actually pretty decent sculpts.
I have several of their dwarf and orc minis (you can see some of the archers and a couple sword-orcs in the Day 4 post).
I spent my gaming allowance for this paycheck on those skirmish pdfs, but after the LOTR orcs are done (and a couple other projects on the burners), I may pick up a pack o' 50 orcs (only £7.70!!) and try converting the bejeebus out of them.
