I weighed all the pros and cons and was really tempted to order from TLA store, but they didn't have the boing I really wanted. It also would have cost me the same ordering from TLA's store as it would from Healthy Bird and HB is Canadian so I felt I should support them. Plus I know the owner of HB and have met her on several occasions.
Lowes, Home Depot, Menards - in the lumber dept. Add ss chain and wa-la! I make the other stuff too but occassionally purchase - very occasionally due to the expense. I shop around for best prices including shipping.
My last couple orders have been through www.customparrots.com. They've got quite a dew really neat toys my birds have loved that I haven't been able to find anywhere else. Customer service was above and beyond, too.
