There are so many alternatives out there it is hard to know where to begin!

First I guess I will repeat the suggestion for one of the Agfa Isolas. I like the II model myself, with the better lens and three shutter speeds - lots of bang for the buck there. (Except that if we keep talking bout them, the "buck" side of that equation is only going to be going up!)
... not a TLR, a folder or a system camera.
Maybe the term viewfinder camera applies - at least that is how I refer to them.
Considering just that type (and not pseudo TLR's, Box cameras or simple folders), you choices include the Dacora Digna, Goldammer Goldixette, Vredeborch Felica (and its many variants), Braun Paxina, Ilford Sporti, Certo-phot, Certo-matic, Arti-Six, and Balda Baldixette, just to name a few. If you don't mind venturing into 620 film, there are also the likes of the Meteor (Universal Camera Corp.), Ansco Readyflash, Sawyer's Nomad 620, Imperial Savoy or Imperial Mark XII. Those are just off the top of my head, and it is a pretty diverse list, ranging the gamut from very toy-like cameras, to ones having surprisingly good image quality. Note that many (such as the Isola) come in multiple versions where one type may be just a simple light box and a meniscus-lens, while another has a better lens design, more shutter speed options and greater flexibility overall. Also, note that some may be rather hard to find, while others are ubiquitous.
