Some will tell you any glass shelf should be avoided.
Some very highly regarded shelving systems including those from Naim and Wilson Benesch use glass shelves.
Unfortunately you will get people on both sides who are convinced those on the other side are clueless. Sorry to be of no help but the effectiveness of things like shelves, footers, etc. are highly dependent on the equipment they will used with.
Buy used and experiment. Have fun.
