Please would like help from you more experienced in the subject ..... ah sorry for the english because I use the google translator .... thank you all.

2:2pcs SBR25 L600mm linear rail +4pcs SBR25UU linear blocks for cnc router 3d printer-in Linear Guides from Industry & Business on Aliexpress.com

This one is the best as it is much stronger:

However they need to be mounted on a more accurate flat surface.

Jonathan answer's your question but I think that price is just for the Linear carriages Only and doesn't include the rail.? You need to check.
