Some of the best WordPress plug-ins I’ve checked out are from Lester Chan or GamerZ.

You can visit his website here or check out his plugins at WordPress’s site here.

His installation and usage instructions are always clear, easy to follow and thourough. I’ve never had a problem installing or using one of his plugins. The concepts behind the plugins are well thought out and GamerZ usually includes many ways to tweak the plugins to look the way you want them to. I’ve installed and checked out wp-print, wp-postratings, wp-polls, and wp-email.
