Doug,
I think you would do well with either a Rolleicord or a Yashica. I have no experience with the Rolleicords, but I do have a Yashica 635, which I've had since high school. I love it, and recently used it to take portrait photos of my wife in B&W - fantastic portrait lens. If you get a Yashica, I'd advise (if you're on a tight budget as you say) to avoid the Yashica 124 and 124G, because they are getting quite expensive, but try to get a model with the Yashinon instead of the Yashikor lens. The Yashinon is a 4-element Tessar design, and reports are it is quite sharp. I like my Yashikor 3-element lens - not as sharp, which is actually better for portraits, I think.
All TLR's tend to benefit from the use of a square lens hood, and many of them used a "Bay 1" type filter/hood attachment. Lots of them available on eBoy, just do some research and find out which Bay size your new TLR uses, and get a lens hood or a Bay-to-Series 5 adapter with a lens hood built in - both work fine.
You might also consider looking at the well-regarded Minolta Autocord series TLRs, although again, I have no direct experience with those, I am simply repeating what I have heard.
Some folks have difficulty adjusting to the fact that you see everything reversed left-right (because there is no pentaprism, just a mirror). But still easier to use than a LF with the ground-glass where everything is upside down AND backwards!
I have heard also to avoid the self-timer on TLR's. If they freeze, the shutter will require an overhaul before you can use the camera again. Don't know how true that is, but I tend not to use the self-timer on mine. I have done so recently, and it worked. But I crossed my fingers.
Some good info on the Yashica's is available here:
