When it comes to canister filters, I don't think your ever going to find the perfect one, no matter what brand or price.
That being said, most will do a decent job for you.
After you are sure the unit will work for you, the next consideration is how easy is it to get replacement parts? Do a search on the filters your interested and find out if you can get replacement parts at all and if you can get most or all of the parts to it. You don't want to have to replace your canister filter because you can't replace one inexpensive part.
If I were limited to the choices in your original post, I'd get the Penplax cascade. If I could get anything, I'd say spend the additional money and get Eheim or Fluval, They are high quality and have a good selection of parts available. They are more expensive, but you'll only need to buy it once.
Lastly, everyone has an opinion on canister filters, so don't feel that any one person is necessarily correct here, including this post.
