Here are the sermons from our church, Le Mars Bible Church. Pastor Fred is an outstanding preacher, and Pastors Mike and Matt are very good as well.
Here is the Faithlife site (including sermons) of UpRiver Bible Church, in Fernwood, Idaho. Pastor Brian is like a second father to me, and is a gifted teacher of God's word.
Here is the sermon page at Desiring God. John Piper's sermons have been, outside those that I have listened to week-by-week in the context of the local church, perhaps more formative than any others.
I haven't preached too many sermons in places where they get recorded, but here a few:
