While I enjoy having a good model railroad book or magazine in my hands to flip through, the price of MRH has made it worth reading.
You can read the magazine on-line or download a copy of the magazine as a PDF for later reference. (I highly recommend high-speed connection for downloading).
There is a good variety of how-to's, layout tours, and columns. Anyone from a beginner to a seasoned pro can find something worth reading in each issue.
The website is http://model-railroad-hobbyist.com/
I really enjoy the "One Evening Projects". The latest one is on weathering. Each article gets an easy to use feedback link like that where you can comment on articles and ask follow-up questions.
If you join their community (free registration), they have a lot of interesting forums with helpful advice for improving your model railroad.
They also offer all of their back-issues on-line for FREE download also.
Since it is FREE there is no risk to visiting and giving the site a look. If you enjoy the magazine check out some of their sponsors who keep it FREE and tell them that you saw their ad on MRH.
