Here's a nice alternative. My green cheeked loves it.
I got mine with my board most mechanicals come with them.
Amazon has this great one though.
Pretty cheap and works well from what I've seen of it.
Of course I don't mind! Here's the link for it. I have 3 of them! Very durable, maneuverable, and easy to clean.
There are a bunch online if you search for bird window perch. This is the one I have from Amazon: https://www.amazon.com/Pollys-Sandy-Window-Shower-Perch/dp/B0040Q85L6/ref=mp_s_a_1_4?keywords=bird+window+perch&qid=1575471806&sr=8-4
they are like this thing https://www.amazon.com/dp/B0013CTFQ4/ except they have a third dimension of travel, also no snooze button, also way louder and faster.
