i've had the same full expedit for over 10 years, no problems at all with it, no bending of the shelves, had loads of use and abuse, whoever told you that is wrong, they're fine for albums.
i use i cube S300-type shelves for 45's stacked on top of each other, again not problems with them. I did find a cheaper place on ebay i think it was when i got mine, they send them plain so you can paint/spray/varnish/whatever, think they were around £16 each at the time. all i have to do is actually paint/spray/varnish/whatever when i get round to it...
