8mm materials

I will be dabbling in 8mm and Super 8 in a few months. I'm slowly acquiring items I will need. To start I will be using Tri-X reversal Super 8 and Fomapan R100 8mm; color may come later. I've most the chemicals I need to mix the solutions - doing it correctly is another story
I have cameras, projectors, a couple screens, and a table-top editor. I will likely purchase a Lomo UPB tank (and slitter for the double-8 film).

Can anyone suggest current (new) products and online vendors for the following in both 8mm and Super 8? (I'm in the U.S.A.)
50-foot reels
leader
splicing tape

I can find these items easily by searching the web, but figured it best to ask for experience-based recommendations.

Also, is there anything else I might need?

Those items are fast disappearing from most dealers stock lists. I have gotten some of both from Ebay Sellers "Moment Catcher" and JMP61.

http://www.momentcatcherproductions.com/ is the first guys non e-bay page. They also do film transfers so they have to order leader and reels in bulk.

Thanx, that will help. I have some of my grandfather's equipment, and while the leader is still good, I don't trust the splicing tape - it's from the 70s or 80s.

Oh Yes, Splicing tape. Their are two kinds of splicers. The "presstape" style that takes perforated tape and the style that punches the perfs into a plaiin strip of tape.

Urbanski film seems to have "bought the business from Kodak" on the presstape splices. http://www.urbanskifilm.com/presstapes.html
