These sturdy shelves are available for a decent bargain again at $159 for a pair.
I actually bought them again last month after watching them for quite a while (paid $179 a pair) but I noticed that they are now even more discounted so definitely worth a deal imo.
I've placed my order for my 5th and 6th unit and I can recommend them; be a little careful assembling them as the joints aren't the best but it's kinda fun putting it together as all you need is a mallet.

boy those joints are awful. I have the Bunnings version from years ago. Still going strong, but I don't like that joint system at all.
