I use a Deardorff 5x4 special, but want to go bigger. The prices have come down a lot compared to a few years ago, which is catching out some people trying to sell now, but a quality camera still isn't exactly cheap.
My full outfit (camera, 3 lenses, spot meter) must have cost me about £2500, maybe a little more, but it is an amzing outfit. If I didn't want to go larger I would expect that kit to be all the LF camera I ever need (excluding breakages or massive GAS)
