I'm amazed at the diversity of the entries, and everyone is a Winner of a different description and intent for <$100.
The innovation and resourcefulness of all the builds is truly inspiring.
After much back-n-forth indecision, (not because I thought any one was 'better' or 'most' for the $$), I finally voted for Micheal's Nucifera (The Violent Squirrel) because of the simple effective design, clean/balanced lines, and it appeals to what I'd rather want to play.
Josiah's Single-cut Fretless 5 - Cedar and Rosewood would've been the second (very close) choice because of the design, looks, best use of avail mat'ls, execution, and quality of appearance for what could be built for <$100. Really well done.
Since all the builds are built to different criteria and for different purpose, they IMO cannot be judged by the same standards, so all entries are Winners in their own category.
