MDF or similar would be ok as long as you aren't using much coolant. If you have any moisture resistant lying around that is a bit more stable in terms of dimensions and changes in humidity etc but far from essential.
You could also just bolt down a small piece where you intend to put your vice, rather than the whole bed. You would just have to re-skim it if you remove it but that's not a big deal for a small piece like that.

So this is the case that I am milling out of EcoCast.
These are the end mills I have so far.
3.175mm http://www.ebay.co.uk/itm/1824106825...%3AMEBIDX%3AIT
2mm https://www.aliexpress.com/item/10pc...608.0.0.EJZ3Jx
1mm https://www.aliexpress.com/item/10pc...608.0.0.EJZ3Jx
The case is like 75x60mm so I don't want to carve that all out with a 3.175.
Was thinking of getting something along the lines of a 6mm end mill to do the main hogging out.
What is the max these spindles can take?
I have collets up to 12mm.
Also, where is the best place to learn speeds and feeds? I have been testing these 3mm on a bit of this EcoCast and broke 2 end mills within minutes.
One I accidentally knocked into the work piece. The other because I did not know how to correctly set up the Z in Fusion CAM.

Have you thought about using foam etc. to practise on that way it will be more forgiving when you dive into it.
