Good advice above on the Deardorff. It looks like a good package. The ad says the bellows are new and the shutter has been serviced ("recalibrated"), so that's a good sign. If you want to hedge your bets, budget about $80 for a CLA on that shutter from S. K. Grimes. I've had them do a Compound shutter of the same type recently (i.e., after Mr. Grimes' passing), and it works great.
If the 18 filmholders are all modern plastic types like the one shown, those are worth $30-40 a piece by themselves. If some are wooden, I'd say those are worth around $15 a piece.
Do ask around and try things to consider whether you really want to get into LF before sinking too much money into it, but by the same token, don't be afraid to jump straight into 8x10". That's what I did after trying out a friend's 4x5, and I feel I made the right choice following my intuition.
