Is Investing in REITs a Good Idea?

Though I do a fair amount of reading of the real estate market, I must admit that I don't keep in touch with domains such as real estate investment trusts. I understand the REITs (as they are called) could be a very useful addition to one's portfolio, especially for those folks who wish to invest in real estate but are not actually keen on owning a house or real estate! What are the views of the members?

I also read that due to favorable tax laws, REITs generally pay large dividends which appeal to investors looking for income and stability. And because REITs generally do not own single-family homes, they usually do not move in lockstep with the rest of the housing market or the stock market, and so if owns REITs and S&P stocks, when one zigs while the other zags, making the portfolio more balanced.

Now the above is what I read...it will be quite useful to know the feedback from the members if they have had experience investing in REITs..

Thanks for your time
