Grafting tool featured in The Permaculture Orchard: Beyond Organic

I heard about this video a couple of years ago, but didn't have it in the budget to get it.  Fast forward to Sunday, I finally got around to buying the download.  It is one of the BEST videos I have watched on this topic.  It's short (unlike Michael Phillips' DVD, which is also an awesome set, just longer and more involved... which is a good thing in it's own right) and has a lot of little nuggets of information.  I really wish that I had gotten it when I first heard about it.  It was the best 7.50 that I have spent in a long time. :)

Anyway, I am in the market for a grafting tool to make it easier for my staff (okay, my children) and I to graft trees.  I know that you can use a grafting knife at a much cheaper cost, but we plan to graft 1000's of trees and I want make it as easy and successful as possible.  We currently live on a 5 acre farm and have +100 fruit trees of various kinds that we will be taking a good deal of our root stock and scion wood from.  We are planning to buy more land to expand our permaculture orchard within the next couple of years.  We want to get started on the trees now.  

We are trying to stay as far under 500.00 for the tool as possible without sacrficing quality.   Suggestions please. :)

Great video-it inspired my wife to get me The Omega tool. It works but it dulls and needs new blades and a rubber bumper after 50 or so grafts. The change isn’t easy and it doesn’t operate as new. Good clean cuts = success. Last Christmas I got knives. I am trying to learn... skewered myself pretty good on about number 78 of 80.  I’d like a true bench mounted unit if I was doing more than 100 a year. Check out the scionon at either grandpas orchard or graftingsystems.com from what I’ve read they seem to be worth the investment. Growingfruit.org has lots of discussion on this.

Thanks so much for the tool review and website information!
