Note that there is no tax on a shopsmith order, whereas where I am at there is 9.5%. Granted, since you are in Oregon there is no sales tax.

When I checked just now, shipping was $8.50 for me on $36 casters.

So total shipped with template (which should be correct, we shall see) is $44.50, whereas my local place is $33 with no template. If you are ordering other stuff I would call it a wash.

Note that the casters I got are, I believe, identical to the SS ones. If you are willing to go with cheaper quality (ie: no ball bearings) then you can probably save some cash and cut the cost in half. There are two main things that you get with the nicer casters - easier to move due to reduced friction, and easier to go over uneven floor. Lower quality casters would only address the second.

21 - Series
PP - Poly-Pro Wheel
30 - 3.0" diameter
G - 1 1/4" width
I - Gray/Gray wheel color
44 - Single precision ball bearing, 3/8 w/Full T
91 - Grip Ring 7/16 x 1-3/8
YY - Generic placeholder for options.

Note that they had to assemble these for me. Baiscally, you pick your wheel and your caster holder, then they put them together. This also means that the same overall part number with the 30 replaced with 40 or 50 respectively should get you 4" or 5" wheels.
