I bought a fairly worn Iston 4x5 woodfield from a CSer for $170. Replaced the broken groundglass with a spare one I had. An old Kodak 203/7.7 Ektar bought for US$110 complements the camera with it's petite size. So about $340 for camera and lens.
Would I recommend you to go the same way? Not if you can help it. I'd suggest you buy a modern day camera like a Shen Hao (new or used) with a modern lens in a modern shutter (Copal/Compur - like boochap's Nikkors) for minimal fuss and good initial experiences without having to fiddle with repairs and fudges because one thing or other is not right with the camera or lens.
There are definitely good lens bargains to be had on Ebay but be aware that many old large format lenses will not have accurate/serviceable shutters unless they've been serviced. There are lots of cheap and nice old glass: Tessars (esp. good and cheap; Kodak's versions in the form of the Commercial Ektars are very very good; Xenars are usually safe to buy), Dagors/Dagor types (Doppel Anastigmats), simple three element Anastigmats, even Rapid Rectilinears, which make very nice pictures, but I have bought few at a good bargain that have not needed some fixes or other.
I once bought an uncoated 180mm Voigtlander Heliar in Compound shutter for US$115. Whilst the glass was pretty decent, the shutter was DOA. It took me 5 long man-hours to fix the pneumatic shutter, work out the jam, give it a good cleaning, and reassemble everything. Was it worth it? Well yes. Some old lenses have a look that make modern multicoated optics look boring when you shoot in B&W. But I wouldn't recommend this to an absolute beginner. There's too much to work on unless you don't mind this sort of thing.
If you're buying old LF lenses on Ebay, do it with your eyes open. Also some scratches and marks won't kill especially with so much film real estate in 4x5. What you should be afraid of is uncleanable haze and lens separations.
