I really like the Ricoh KR-5 - there were 3 versions, all good. They can usually be found on the 'bay for $25-40 and they are quite nice. Essentially, a more compact, lighter version of a Pentax KM or KX - with a few more features than a K1000, including more viewfinder info and depth of field preview.
I wouldn't consider the Ricohs as an off brand - they were not copies of anything, and had nice ergonomics and nice features. IMHO, they are quite legitimate alternatives to the Pentaxes.
