Is it common to find dedicated server trials or first-month special offers?

I noticed a few providers offering ultra-low pricing just for the first month of a dedicated server.
Are these legit, and who else is doing this right now?
What dedicated server host is better: HostingSource.com or GTHost.com? Why? Any reviews?

If you’re looking for really good service & support, signup with Hostingsource.com dedicated hosting service. One of the best things from this decent host is the impressive, fast and very professional guaranteed 24/7 support, within one hour, guaranteed - I never wait for more that 10 minutes for a response. This is true!
1st MONTH special price looks great!

not really - dedicated boxes are expensive to run, so most providers don’t hand out free trials like candy
you’ll sometimes see “first month half off” or “setup fee waived” - that’s about as good as it gets
