Linear Bearings....Where ??

HI... My Name is George and I come from a very small island in
Europe.... Malta.

I am currently looking for sources to build my first XYZ CNC table.

Therefore, I need some help regarding where to find and purchase
linear bearings to be able to set up the table. I already purchased
the antibacklash leadscrews, motors, driverboard, and router.

What liner movement has worked best for you ?? and where did you get
it from?

Thanks

George
