If someone was interested in purchasing a breathalyzer for personal use this could be done easily online. Amazon and Best Buy both have these available for purchase on their websites. They even have a key-chain version of the device. As for when someone would purchase one, that would be up to the individual and what their needs are.
It is very safe to buy a breathalyzer if it doesn't have any side effects from use. It is safe, but for best results you should purchase new. A used one could be damaged.
Alcohol breath testers are available at both online and offline retailers. For an online order, one can use Amazon or Ebay. Many bars and restaurants have alcohol breath testers that they allow patrons to use.
AlcoHAWK Slim breathalyzers can be purchased on the Breathalyzer website, but they can also be bought on Amazon, Q3i, Walmart, Best Buy, Walgreens, and many other great websites.

If you've driven into your home, I don't think a breathalyzer is really needed. That aside: Yes, you can be arrested for drunk driving/public drunkenness without a breathalyzer test being done. However, if you were asked to take a test and refused, the police would report that and it would be used against you. So you should do the same to them: "I asked for a breathalyzer test, but they wouldn't give me one!"
The benefit of owning an alcohol breathalyzer is that one can check to see whether or not they've been drinking enough and should stop, or if they should not drive.

"You can buy your own alcohol tester from a company called breathalyzer. They are also available from alcatester or hwsensor, as well as from amazon. They run about $35 to $40."
No, or else there would be a bunch of drunks on the road popping penicillian.
If you were driving and the breathalyzer detects alcohol, then this would be considered a breach of your probation in most states in the US and provinces in Canada. You would be arrested and sent to jail, and your probation officer contacted.Added: If one of the conditions of your probation specifies NO alcohol, you don't even need to be found driving. Just drinking it is sufficient for a VOP.
I saw an episode of Mythbusters where they tried to beat the breathalyzer using tactics rumored to lower the reading. The results of their tests showed that none of the products worked except one (of which I can't remember the name). It actually made the breathalyzer read that the person had an incredibly dangerous amount alcohol in their blood. They did not try medication, but it is safe to say that there is no way to reduce breathalyzer results if you have had too much to drink.
To pass a breathalyzer test when over the limit one can suck for the bag instead of blowing but of course this might be noticed by the officer. It is illegal and irresponsible and one should simply avoid alcohol to pass a test.
