I can't remember for sure which the four were but ithemes, gravity 
forms, All-in-on-SEO pro, shopp, getshopped, phpurchase, wp-member, 
WishList Member, wpjobboard and gdpress are all premium plugins I've 
looked at recently or own.  Then there's also everything at 
wp-plugins.com.  I'm sure there are top n posts out there for premium 
plugins...
