Tubing straightener?
Anyone know where one can get one cheap? Just don't feel like spending $200
Bux.. Or maybe there is an alternate method... I hate to fab one that looks like a snake...

I'm guessing you already own a tube straightener. Cut the tube to length. Straighten by hand as best you can. Lay on bench. Cover with a 2 x 6 or a piece of shelving or whatever. Press down and roll back and forth. Here's a photo.

Unroll it on a flat surface
What worked for me was to hold the tube roll vertically on a flat surface (kitchen counter?... Don't tell Shirley!). Then hold down the tubing end and unroll what you need as you roll the coil along the flat surface. Works really well...sorry no photos.

Or...
... you could toss that 3000 series tubing from Van's and use 5052-0 tubing instead. It is a better material for the job, especially for applications with significant pressures like brake lines. And conveniently, 5052-0 tubing is typically sold in straight sections, not coiled.

Get Sliding door rollers
Get some sliding door rollers from a local hardware store, mount them to some angle and clamp it in a vise.

+1 for 5052
Ditto what Tom and Roee advised: use straight 5052-0 tubing.
I just replaced an oil drain line with new 5052, complete with double flare, three 45 degree changes, and a bead; for a novice like me, it's very nice stuff to work.
After completing the fabrication, I found a replacement online for 10% of what I'd spent on tools, materials, driving to a supplier, and building the line twice  .
My final version is distinctly non-snakelike.
YMMV

Hmmm... I particularly like the door rollers, looks like the same idea as this one http://www.eastwood.com/tube-straightener.html...
Off to Home Depot, Thanx all!

Better yet, practice your bends with the 3003 and then do the final install with the 5052.

I have always used the "rolling pin" technique described below. Works just fine.
