I usually buy the birds toys at PetsMart (no affiliation.. just a satisfied customer) but decided today to try someplace else .. a 'just birds' store.
I not only found a few different toys .. I think I found Isabella's next cage .. the one with which she came is adequate (24W X 29H X 19D), but I've been wanting to upgrade. They had a powder coated King cage (33W X 41H X 26D) for $450. Does that seem reasonable size-wise and price-wise?

oh cool @ the new cage
I have one kings cage but I got it with my U2.
I am pretty sure thats a resonable price tho.

Ooh I love King's Cages! Casey has one, they're great! I am pretty sure that is a very reasonable price... you can check out their website and compare some prices.

i found one on petstockroom.com that's a little smaller, but it's still pretty big (30x32x60) and it's under $200. it ships free, too!

Thanks for the replies.
I visited the King website and the price is very reasonable.
I try to avoid 'impulse' buys and like to support local businesses whenever possible. I'm feeling another trip to the shop is in order.
Oh.. did I mention they have the cutest babies in the Nursery?
