Straight Edge for Jointer

I have been a busy boy!!!!

Picked up a used R4511 a month or so ago. Found a new Bies fence on CL for $200 to install that my wife brings home today…which is great because the saw came with a router table extension that the base R4511 fence will not support.I picked up a Grizzly 1182 jointer off of CL. I paid $180 for the jointer, a Skil scrollsaw and a 10” Skil bandsaw. I sold the Skil bandsaw and my junk benchtop jointer the same day for $100 so after all was said and done I have a little over $100 in my jointer and a new scrollsaw. I haven’t used the scrollsaw buy hey it was basically free so I will find something to do with it.

Back to the straight edge….The jointer works pretty well for the price. I have new blades coming and I want a way to accurately set it up. I have purchased a Grade 0 square from Grizzly that will arrive with the blades so I can get the fence right.

Do you guys have any suggestions as to an accurate straight edge? I plan to set up the jointer and use it to align the TS wings and the router table extension. I have seen a 36” Woodpeckers for $54 (free shipping) and it claims accuracy to 0.001” / foot. I think there is a review of a Garrett Wade 38” that claims accuracy to 0.002” for the entire length. I like the price of the Garrett Wade at $25 ($35 w/shipping).

Do you have any thoughts or suggestions?

Thanks
