Old dental tools are great for sculpting.
Also, I am compelled to suggest online discountretailers whenever I get the chance, as I only find the hobby to be tolerably priced at 25%-35% off:
http://www.maelstromgames.co.uk - Consistent discounts, extra discounts on 5+ 'army bundles', free international shipping, great selection. Used as #1 seller by myself and several other users.
http://www.chaosorc.com - Good discounts (particularly on large items), cheap shipping. patchy selection but carries lots of older products and non-GW stuff. Some items aren't clearly labeled differently from older versions, but they're a good alternative on specific items.
Battlewagon bits is right now pretty good for getting individual pieces and there's good prices on boxes as well, but sometime soon they're removing the online component of their sales and switching to phone-in orders and downloaded PDF catalogs, due to GW's outdated policies on buying online. Which is quite the hassle, but doesn't exactly stop people from buying online, either. So it'll just be a pain in the ass without really changing anything once it happens.
