Ebay is the best place to get rails. But, you have to watch out for prices. I paid about $499 for a pair of new THK rails that were 8' long w/4 bearing-blocks. I saw the same thing go for $800 a week before and after. Sometimes you just have to wait for that perfect item and price.
Also, if your looking at THK rails, the shorter the rails the much smaller the price. I picked up some 14" THK rails w/6 bearing-blocks for around $20.
THK rails are affordable, but you just have to wait for a good deal (several weeks).
If you need really cheap go to thomson shafts and such. |
