would blinc suit you? its not really one of those ones that gives you massive black spiders legs, but it doesnt run or smudge. Its not like a standard mascara in that it 'peels' off under hot water. The cheapest samples I have found are here (you can get both an eyeliner and mascara sample for free and just pay for the £2.75 postage)
For a good basic black mascara without spider eyes, I think you'd like the original Maybelline Great Lash. It's only £4.99 (on promotion at 2 for £10) and gives really good definition. It's one of those 'cult' beauty products that's very cheap but does the job and I think a lot of top make-up artists swear by it.
