Pellicle,
There is of course the Super Ikonta C (with coated Opton tessar) which is 6x9 and has quite a passable lens particularly at apertures smaller than f8. It is lightweight and folds up into a tidy package. It can be focused by it's coupled rangefinder, which is handy. I have used mine with good success up to 12" x 18". The prices for these seem to be all over the place but it is a very nice camera if you get a good one. I always use a tripod, lens hood and cable release. I will often take mine with me on backcountry hikes.
There is another camera that is often overlooked and that is the Moskva 5, also 6x9. The lens is coated, the shutter is very robust and accurate and the coupled rangefinder works well. The camera will sell for less than $150.00 on Ebay. Search: (moskva,moscou,moscow,moskba,mockba) 5 Camera.
It is a FSU camera and may be easily available to you. I have one of these and I'm very impressed with the utility of it. If you get a good one, you will be pleased. It is more rugged than the Super Ikonta but if it did get lost or broken it is easily repaired or replaced.
Again use a tripod and lens hood. This is worth a try.
