i don't think there are any tripods that meet your requirements ($200, ballhead, good for a pentax 67).
what would you rather compromise on: price or ballhead?
Well, actually. I sort of disagree. If weight and portability aren't critical (and apparently, they're not, in this case) one of the best kept secrets in the market for rock solid affordable tripods is a vintage Linhof. Granted, they also made fairly lightweight types which would struggle with a P67. But their medium and heavy duty offerings are certainly available for under $200 in most locations. I'm in Australia, and a few years ago I had one posted from the US and it still set me back under USD 200 all up. Mine is a medium duty type with pan and tilt head but is
easily capable of supporting my 4x5" Super Technika. Plenty of them were fitted with various ball heads if you really must have one.
It's true that Linhof no longer service or even stock many parts for their older model tripods (although certain parts such as some of the knobs and camera fixing screws are still catalogued and surprisingly affordable, even if the paint scheme may not be period to your vintage example). It's also true that all but their lightest and cheapest options were built like the proverbial brick ****house. Find yourself an example with good paint that's been little used or well cared for and it will still have a hell of a lot of life left in it.
I have a lightweight classic model perfect for 35mm rangefinders, SLRs up to medium teles, TLRs and even my Hasselblad and 80mm at a pinch. It's Linhof ball head has their wonderful reversible plate with 1/4"–3/8" thread on one side and straight 3/8" on the reverse. A godsend with my Contax rangefinders or Leica stuff. The larger one can handle anything else I'll ever use.
I don't yet have one of their twin shank super heavy duty models (derivatives of which are actually still in production today for a price of thousands of dollars, depending on column and head options etc). But I wouldn't mind one a bit. So don't be at all surprised if this post disappears in a day or two because I'm not done buying them myself yet. But if you want something rock solid at a bargain price they are very hard to beat and feature the best looking maker's badge in photography.
