Do AutoBlogs such as wp-robot fair in serps OK still?

I have never used an autoblog, but now I have quite a few sites on the go I am tempted to try one out on my less prized possession?

How do these stand now post penguin? Do they still hold rank or does cutts and co have there days numbered?

wpr with the best spinner works <> only if the settings are for higher spin replacements i never had any probs on the few of my sites using this plugin

So is the inbuilt php based spinner no good?

I don't think I want one enough to buy both the plugin and a best spinner subscription.
