Otterella, all my gear is listed in this thread
I am selling my Keggle with fittings installed, which would certainly be big enough for anything up to 10 gallon batches, and is excellent for all-grain. Pictures are available in my gallery titled "Keggle." I do have one guy who is potentially interested in it.
I don't have any carboys, but I have had great luck fermenting in 7.5 gallon AquaTainers, which also allow for no-chill brewing. I'm selling 2 of them.
Unfortunately I had to retire my mash tun about a year ago and have been doing Brew-in-a-Bag since then, but I have sold my bag.
