I have both the ikea type for a permanent set up and the folding ones for taking to retreats/crops. (both a 4 foot folding one and the 5 foot!). I would not want to ALWAYS crop on the folding tables, for all the reasons stated above. They just do not feel sturdy enough and there is some give. I like the white melamine type from Ikea...I used the desktop from Ikea and attached it to two small bookcases for support rather than legs (giving me storage on both ends!). It is also a TINY bit higher than the legs would have had it. This came out a bit like the project tables from PB (a very cheap version!). Love it.
