A cheap Yashica or Minolta, or even a Rolleicord for the right price, would be a good and inexpensive choice if you just want a simple camera with a normal lens. Adding a set of quality close-up lenses (e.g. Rolleinar) for more versatility is well worth it IMO.
However, IMO, a Mamiya C series TLR gives you the most bang for your buck in a TLR, by far. The C series by Mamiya would be more versatile than the aforementioned fixed-lens cameras, if that is something you care about. You can usually get a kit for around (or sometimes well under) $200 U.S. The lenses are superb IME (though I have not used every one of them; only the 65, 80, 105, and 180).
