Clubs: "As God is my witness, I'll never pass Airflights again!" - Scarlett O'Hara
http://www.renegadejuggling.com - Renegades baby. Why oh why did I wait so long! These are the best clubs I've ever passed. When I ordered mine (after long internal debate regarding the substantial investiture in three high-quality clubs), the guy from Renengade Juggling was really helpful. You see, there are a lot of choices to be made when buying Renengades. Color, weight, taped handles or not, foil patterns, etc. Now before you go and buy some wacko ultra-heavy, solid granite, teflon-handled, inverted-mobius proto-club think about what you are going to do with them. Honestly, I bought mine for passing with others, which means buying "the standard" i.e. 95mm (bulb width). Outside of that, go crazy! The color selection is complete and decorating options are plentiful. I chose "hardbody" (at no extra cost) which is a harder plastic and seems to be holding up really well.
CigarBoxes: "If at first you don't succeed, try, try and try again. Then give up. There's no use being a damned fool about it." - W.C. Fields
http://www.infiniteillusions.com - These boxes are nice if you don't mind a little larger box. They are thicker (from front to back) than any others I've used, but are more sturdy. Made from solid wood (not ply), all the joints are dovetailed.
http://www.dube.com - I had some of Dube's wooden boxes for years. Eventually, the ends were so crushed, they were pretty unusable. But, they do make plastic ones that I would like to try someday. Problem is, the one-piece plastics are almost as much $$$ as the wooden ones!
DevilSticks: "The Devil finds work for idle hands." - Proverb, 1721
http://www.dube.com - Their "Trigon" devil stick is my current favorite - long, thin, and just heavy enough. Probably not the best for the beginner (the devil stick itself is not rubberized). Also, their current handsticks are covered with some kind of space-age silicone that lasts forever.
http://www.toddsmith.com - Todd Smith sells a great devilstick covered with a kind of cloth tape. Great stepping stone prop (or beginner prop for that matter) from an easier, rubber coated or dipped devil stick. Also, this would, I think, be a good prop for "flower-stick" jugglers who want try something harder. Definitely not for performance (looks pretty lousy). Also, whatever cloth tape I had on mine degraded after several years (the adhesive started to slag). But by the time that happens, you'd be ready for a nicer, shiny, mylar-covered stick anyway!
YoYo: "Those who make peaceful revolution impossible will make violent revolution inevitable." - John Fitzgerald Kennedy
http://www.extremespin.com - After meeting Brian Trump at Hugo, I took his recommendation and went here for my yo-yo needs. I just got an order from these guys and they are great. Super-fast delivery and when I noted on my order that I wanted blue yo-yos (instead of red like in the picture) they were right on the money. NOTE -They do not carry Came-Yo brand yo-yos. I was looking for an injection Mondial and will have to find it somewhere else.
http://www.infiniteillusions.com - I met this guy at Groundhog's Day 2000. While they have many juggling props, I think their focus is yo-yos now. I bought some strings and parts from here once. While the shipping took longer than expected, the order was complete.
