Not sure how you personally define "small body archtop". I have been gravitating towards smaller body archtops for sometime now. For me, since the majority of classic archtops are 16" to 17" at the lower bout, I consider 14.5" to 15" small bodied.
Below are three that I have acquired over the years
1. Ibanez GB40TH - 14.5" lower bout, 2-5/8" body depth (at the rim)
2. Eastman AR603CE-15 - 15" lower bout, 2-3/4" body depth
3. Ibanez Artcore United AG195 - 14.5" lower bout, 2-3/4" body depth
(Whoops! Corrected body depth measurements.)
All three sound wonderful. They feel so comfortable to hold as well. Of course, to each his/her own.
You can get an Ibanez AG for $400 on eBay give or take.
Good luck in your search.
