Nowadays it is so easy and inexpensive to get started with a CMS style site, I am truly amazed that smaller businesses are still using HTML designers and site builders. (yuck)
Yes a short time ago Content Management Sysytems (CMS) were very, very and I mean very expensive. But hey so were computers. I paid $900 dollars for a Pentium II Processor back in the day. NOT THE COMPUTER, JUST THE PROCESSOR.
Well times have changed, I can get a amazingly fast COMPLETE computer for that same $900 bucks and you can get a killer CMS site for about the same.
A CMS site has so many benefits over a standard HTML or "site builder" site, that I truly believe you are throwing your money away if you aren't using a CMS.
