Or McMaster Carr even, but the HiWins are a bit cheaper.

Chech here... http://www.techno-isel.com/LMC/Products.htm I have some of these... Awsome.... Much better than bearing type slides.. I have hiwins too... The differance is my techno gantry can be disengauged and a light push and it'll travel the 10' easily http://www.techno-isel.com/LMC/Products/Iselrail1.htm ... My hiwins would require a constant force...

I have these on my Z http://www.techno-isel.com/LMC/Products/IselRail300.htm

Good luck

The difference is low to moderate loads for those. Still quite capable in a router I would think.
I get fair travel speeds and accuracy on my router with a heavy gantry just using roller skate bearing on some cold rolled steel.
It is a semi production machine. I run it at most a couple days a week now.
Certainly not as long lasting, accurate, smooth or rigid as linear rails, but a heckuva bunch lower cost.

I am using THK's on my newer builds though. They are nice to work with and very reliable.

I find new old stock on Ebay often. I check for specific sizes.
I bought 10 brand new trucks in one auction. I bought an actual rail from THK online, but have seen and purchased more of the same on Ebay.

It is fine if you have time to watch for what you want.

Other than that, I would go with Hiwin's. They are pretty nice too. I did get one set of those, but haven't yet put them in action.
