Dividend-paying Stocks

Hi all. I have some money I would like to invest in dividend-paying shares. Does anybody have some tips what sectors/shares would be a good long-term investment? A friend of mine advised technology and biotech. Any opinions are welcome.
What I forgot to mention: ethical investments only.
What a weird coincidence. You might be interested in my new business that I just started. There is a low cost subscription based newsletter that is designed to help readers identify morally sound dividend paying stocks which I believe are attractively valued. You are welcome to check out the site here: http://wisdomsreward.com/ The subscription product I mention is found here: http://wisdomsreward.com/category/dividend-focus/ But there is a lot of free content and I am adding more as quickly as possible.
I would suggest that dividend paying stock are not that worthy. U can even invest in non dividend stock because that will fetch u more and the value will increase much faster
