Here is a $200 rack that has adjustable upturned brass spikes for all of the shelves. It looks to be pretty much the same as my older Studio Tech.

Other than upgrading the shelves my easy tweak was to mig weld the frame into a one piece unit. I did it for free @ my auto mechanic's shop and the welds (16 total) took but a few minutes. One piece racks with adjustable spikes for the top shelf (only) cost hundreds of more dollars and from what I have seen in local showrooms are not as square as mine (I set it up on a sheet of glass, sans floor spikes, before having it welded).
Studio Tech stopped production of the models with adjustable shelf spikes shortly after I purchased mine (a few years ago), but it looks like they are back.
