Plugin to Output Simple Front Page Post Excerpts w/ Thumbnails?

Anyone know of a plugin that will consistently output front page post excerpts with thumbnail images, regardless of whether the post author uploads images, imports an externally hosted images via url, or does the same with videos? I've got a multi-author blog and I'd like to simplify it for my authors so their is no need to mess with the "insert more" tag, etc.

(I've tried several excerpt plugins and plugins that limit images (as well as my theme's excerpt settings and image limiter) but they all seem to have holes in them. My theme is Atahualpa (soon to phased out in favor of a wpmu dev theme) and I tried auto post thumb nail, fancy excerpts, advanced excerpt, get image, wp smart image II, max image, and probably a few others. With all, I had pieces of code show up in the excerpts, double thumbnails, and other weirdness. )
