Workbench/Heavy Duty Table Prices and where is best to buy from?

I am looking for a heavy duty table (2 tables) to put a CNC Router and another for a Laser cutter. Both are pretty heavy. Would a workbench be my be best bet, or is there heavy duty tables i can get?
Also, what sort of price range can i expect to pay?
I have looked around and so far i am drawing a blank as to which is the better option for me.
These are way out of my price range - http://www.axminster.co.uk/benches-vices-storage/benches/woodworker-s-benches
I am not sure which would be my best option of these (Butcher Block maybe?) - https://www.murphyworkbenches.ie/collections/all
This does not look like it would be sturdy enough - https://www.amazon.co.uk/VonHaus-Boltless-Workbench-Worktable-Shelving/dp/B00LPCQ82Q/
Similar with this - https://www.amazon.co.uk/d/Workbenches/Dirty-Pro-ToolsTM-Workbench-Pegboard-Workshop-Capacity/B01LD163BY/

And finally this looks like it would do the job, but if it is only $50 in the U.S., then surely i could find it for a similar price over this side of the Atlantic?
It is €150 delivered including taxes to Ireland - https://www.amazon.com/gp/product/B0030T1BRE
Preferably €115 delivered from eBay with taxes paid etc. - http://www.ebay.ie/itm/272480378567/
Is that a decent price? Or could that be bought here for similar to the $50 asking in America?

Or are they even any good?

Sorry for the billion questions, i do not know what to be looking out for, or the normal going prices etc.

Edit.  I just realised that the wood does not come with the one from America.
