and my favourite, cos they are just down the road and let me play with their magnets 
http://www.magnetic-force.com.au/
the neodymium ones should be ok for what you need... strong, small, and nickel plated.. just dont use them in reducing atmospheres , 10mm dia x 3mm = $0.96, or 8mm dia x 5mm $0.96
i use the 8x5's.. strong little fuckers not so good for fridge magnets unless you have strong fingers.
they are good to abut 80deg C only.. if you need higher temps, then go for the samarium cobalt ones..
10mm dia x 3mm = $3.10
AlNiCo are far better for temp (550) but are exxy...
specs http://www.magneticforce.com.au/Specs.htm
hard drive are typically neodymium, and are good.. but they are also pretty fragile... if you let two neodymiums slap together, you can shatter them.. part of the reason they have nickel coatings
hmm, i wonder if they can send magnets thru the post
oh, and can you tell i've looked at this before? needed some for 'adverse atmospheres in furnaces' at uni
