I am not endorsing this listing, nor do I have any affiliation with it... Just want to get the info out to my fellow Pentaxians!
I always search Craigslist and eBay for used gear, along with my favorite: PF Marketplace.
Anyways, I came across the FA Trio the other day for an asking price of $1750 for all three. Items are located in Washington DC for local pickup, but I'm sure the guy would ship them out if you are not local.
Seeing that this is a metropolitan hub, you could even come visit, buy the Trio and spend all weekend shooting in DC, lol
If you're looking for the Fab Three, check it out. I wish I had the money for such an addition to my bag...
