The '030 is quite cheap, here was my way of "cheap" but not the last One offcourse.
First I got an '040 with a terrible fan noise, then a trade in for little money Apollo (great) '060 with 16mb ram, I changed it to 32mb (should get SCSI mod, and another 32mb+ socket,(anyone)?), then (not telling about All clockpot expansions etc.....

ZorroII and a tower. Then a Cyberstorm 3d which never worked for me as it was for A3/4000(Sold it goddammnit). Then.. A PicassoIV Graphics Card and finally (huh) A1. (History part 6/12 maybe? for now)
Best luck for Your slot, the extra mem is only for gaming and demos I think? Use it for PPC,BVision and... Veery expensive.
