Richard, you might want to keep your eye out for a Yashica TL Electro camera. They're super cheap used, they're great cameras, and sometimes come up here on APUG for sale. If not, you should be able to find one on eBay or elsewhere very inexpensively. I understand your reasons for getting out of 4x5, but your 4x5 gear is worth so much more than any screwmount camera system is likely to sell for.
