You want to scrap the whole website/blog or just getting the latest blog posts?
Have you tried something like "offline explorer pro"? They have a 30 day free trial of the software if you want to give it a shot.
Have you heard about wget? It's free and can run from VPSes.
You can use wget to download the whole site.
See this post I posted a while back for how to do it.
Hope that helps!
Are you wanting to grab a whole page or just the articles?
If it's just the articles, then even if you've grabbed the whole page, to automatically strip the article, you need to figure out the tags the article is between to strip out the actual article e.g <div id="article">some text...</div>

There's a Jr VIP Neta10 who has a paid scraper that may do what you're looking to do. I haven't used it to pull content but you enter the tags to search between and it can pull content from between the tags.
I too use httrack. its very usefull and you can download with the filetype that you want.
