I can't stand them (or anything with more than four legs for that matter).
They make my skin crawl and I'm not ashamed to admit that I have, in the past, had to sleep downstairs after I lost sight of one in my bedroom (how about that statistic that everyone eats 8 spiders whilst sleeping in their lifetime??). I have also, on occasion, had to call in my mum/girlfriend to catch them (as well as other assortments of insects and bug-like creatures).
The thing is, I don't even know why I'm so scared of them. There is nothing that I can remember that would indicate where it started, from my earliest memories I was terrified of them and I will be until I take my last breath. Yes, they do have a purpose, I just wish they would conduct their lives well out of my living space.
I can honestly say, if someone offered me £1,000,000.00 just to allow a tarantula to crawl up my arm for 30 seconds I'd turn it down flat.
