i've ordered from Vesalia myself and not had any problems.
anyway, the only reason it's recommended to have 2Mb chip ram is so you can fit lots of nice hi res screens and lots of colours on your new VGA output device.
on an ECS chipset, i find its really a bit of a bind running in hi res, as it cripples chip ram access speed. so run a normal "medium res" screen on my A600 and A500, and my A500 switches between 0.5/1/1.5/2 Meg chip ram depending on what i'm doing to it, with no adverse effect on the Indivision.
so if you can, i'd got for it!
