Thanks for the invite.
I've been here a few years as a lurker, and have directed people here from the Design/Development subforum at RPG.NET.
I am at the point where I want to procrastinate, and I find that reading other people's stuff helps me procrastinate.
I should be writing bestiary entries for some standard fantasy monsters, but I am just not feeling motivated.
As to "which ones caught my eye".
Nights of the Crusades: Just read it, really liked it.
Old School Hack: Read it a few years ago, liked it then.
The Shadow of Yesterday: Read it a few years ago, my game is inspired by it.
On Mighty Thews: The link to the game didn't work, searching revealed it is available for $5.00. I read some reviews of it including some interesting stuff about the cover art.
Talislanta: I wasn't familiar with this, even though its been around forever. I looked at it. Some nice mechanics, but too much setting (too many races, too much focus on minutia of weapons/armor).
I really liked "Dungeonslayers", but I didn't see it in the database.
Vhraeden. Blood, Steel and Iron Will: Oh my god the amount of work that went into this. I was impressed by the quantity, but again the rules were so crazy fiddly, and a lot of it seemed like filler.
Basically I was looking to see what other people had done with their bestiaries, and I am not seeing much at all.
