I've bought 4 total from this seller on
eBay at $39.99 shipped, most recently in January. I dunno why the price has gone up so much, looks like they aren't taking offers on it either. $45.99 seems a little steep, but if I desperately needed one, I'd probably still pull the trigger.

Quality is excellent, although $45.99 is definitely steep. Wasn't exactly a bargain at $39.99, I felt.
Used to be able to get the 1000 chip birdcages on
eBay for $39.99 shipped too, but I haven't seen them that cheap in a couple years.
