I've been pretty happy with the EliteDesk G3 I got off eBay a couple months ago. I actually use it for light work (mostly spreadsheets and emails) too.
I think I paid less than $130 including shipping and sometimes it (anecdotally) has better performance than my home PC which is a full tower I bought new 4-5 years back.
