good links are found only after a quality research. without proper work on the links, you really cant achieve them.
find some do follow blogs like bluehatseo and start commenting(but please not spam any blog). Commenting is always a good method to create good free links. try some directories with link exchange or hire a good SEO.
I generally use services to send out links to directories, but manually submit to local and business directories in my niche. I mainly do article marketing, social bookmarking and focus quality time and effort in gaining links from guest articles on prominent blogs in my niche. Other places to get links from with articles are web2.0 properties such as hub pages and squidoo, how to and wiki sites as well as blog commenting and videos. If you have the budget and something worthwhile saying then press releases are good when you use services like PR Web and 24/7.
You should also try a private link exchange network. One that has 3 groups that give each other 1-way links.
As a noobie to SEO I have read on Google that they prefer you to NOT buy links. I would like to buy a link but am too worried my site could get dropped by Google. Can Google tell if a link is bought?

I think getting good backlings is only possible if you have good and original content. Then you'll have natural backlinks.
In our case, they were provided by an SEO company. My employer just purchase them. However, I observe that there are only about 8 good links for every 100 PR 4 dofollow links given. Sometimes, it's waste of time and money.
OP, if you are asking that question, you really need to learn about backlinks before you start investing any money. If not, you will get burned more times than you will care to remember.
