Hi all ive built my cnc and it works ok but i have some crap mdf as the table bed but boy is that got some bend in the middle say 0.035".

ive got the rexroth stuff as part of me frame but i need to bye

45x90x1000mm but the catch is i need 9 of these totaling about £250 from RS or marchent dice thats just to much money.

is there a cheap place to get this or is there somthing out there that is just as good?.

thanks all in advance.
