go to petco.com or petsmart to get a good estimate I did this many times when I was considering a bird - click on everything you want and add it up.
Only disadvantage to these are when they poop on them, what a pain to clean.
And what you get for Bucc, you'll have to get for Kito ... £29 x 2 = £58 ($114 approx)
Perches are another very important purchase that can cost a bit of money, you will need more then the little wooden ones cages come with. You want some varying in different sizes
Acrylic make great toys (my little buggers won't play with them though so I go through toys quickly)
I got a name its Captain Cracker!! and I'm going to try to get him\her in orange but if not thats OKgreat while don't u post apic of the cage? I would love to see which one you pick out - have you got a name yet? what color parakeet are you getting?
