Does anyone have experience with a good (and preferably inexpensive)
fox kit that has a range of atleast 30 miles? I don't have a frequency
range in mind, and am open to suggestions. Any additional suggestions
regarding the best equipment/antenna to track it with is also
appreciated.

Thanks in advance!

Since you specified 30 mile range, I am guessing that you want to track in
vehicles. The local champ here used a 4 antenna array on the roof of his car
feeding a phase detector that would light up one or more leds set in circle
that showed the rough direction , as he got closer he would go to a
handheld null loop antenna. When it was a matter of feet away he would put a
radio into a sheilded tube with an open end and use that to get the last
couple of feet to the transmitter.

Other teams here tried 3 element yagis and 2 element quads held out the
window of their vehicles and one experimental setup had a rotating yagi
feeding a crt similar to a radar setup. These were used in county-wide fox
hunts with one team acting as the fox and the others acting as finders. The
fox radio in these hunts wasn't an automated fox, it was a team transmitting
on a set schedule and frequency from their vehicle. After each fox was found
another team became the fox and drove off to hide and start transmitting.

The last useful one here was years ago when a packet station got stuck on a
local repeater input and wouldn't shut off. It was tracked and turned off in
a matter of hours.
