Server to buy as I plan to host a blog ...
 

I want to host a blog and I wonder which plan I have to sign up with - canspace.ca or hostsailor.com? Any ideas?

I think that would be cos-effective to have small and better unmanaged dedicated server.

Have a look at servers from time-tested companies - hostnamaste.com and host4porn.com as they are cheap, reliable and solid. Helpful, friendly manner, prompt reply.
