When selecting aluminium plate for gantry sides etc. do people tend to use the most expensive Ecocast variety, or is the the 6082-T6 type OK to use instead?

Are you more likely to get perfectly flat pieces with the Ecocast?

You only need Eco cast or ground plate for critical surfaces like bearing plates or Z axis etc that require parallel surfaces. Gantry sides are not so critical in terms that they need to be perfectly flat or parallel surfaces. Thou I find the difference in prices isn't always huge and the cast plate is so much nicer to work with so I just use it for everything.
