I completely agree. Ticklish Merchandise (from realtickling.com) is amazing, and not only does that blonde cutie get tickled unbelievably thoroughly and skillfully, it also contains a quick sequence of the very leggy (and friend of TMF!) Kristen Lea getting what she says herself was the worse tickle of her life. A definitely satisfying first purchase if there ever was one! The last few titles from Real Tickling look unbelievable as well, though I don't have them yet.
There's alot of great videos out now (compared to what it was like only a couple of years ago!)...it would be hard to list them all! Each company has it's own style, there are some dud titles in most, some more than others (but even that has improved drastically in the last couple of years!). I would pretty much stick to Real Tickling, Paradise Vision (Pit of Torture, Cop Kitchy Coo, Spy Interrogation come to mind), Magic Touch has some amazing videos and is very different in style (it's not acting at all whereas the others, excepting ANA, are nearly always "plots"). ANA, Harmony, FM Concepts can be spotty, and CalStar even more so, but all of those companies also have some great titles or sometimes, specific sequences!
Hope this helped!
