The new cage for my African Grey arrived today and I thought it might interest you for your Suns. It has 5/8 bar spacing, which would be good for them, 4 food/water bowls and a nest box door. It also has a playtop, but it doesn't bolt down to the top of the cage. Conures probably wouldn't cause it to move, but my Grey might. So that I have to do something about. But, otherwise it's a nice quality cage for the money ($190 shipped), with what looks like good quality powder coating and good stainless steel allen head bolts. It even has a shelf at the bottom where you could keep a cage cover or bird food or whatever supplies you would like. I'll post a photobucket link shortly so you can see it. And if you like it, I'll find the ebay info for you. When I tried posting the ebay link though it didn't work. You might have to PM me your email address so I can send it to you.
Oh, the seed catcher was a little bent on the corners, from packaging and shipping, but it is easy to fix if you got one that way. I don't actually like to use them myself as I find they are a pain to take off all the time to get the stuff that gets stuck. I'd rather it just land on my floor where I can easily sweep it up. I took them off all my other cages years ago.
It does have an actual top so you can hang toys from it and you can use it without the playstand tray in. I have it out actually in this picture to let more light into the top of the cage, but it does come with a second tray to catch bird droppings and food while they are on the playstand.
I wasn't completely finished with assembly yet as it was starting to get dark and I just wanted to get a pic real quick. But it has 4 inside food/water bowls and 2 for the playtop that I hadn't put on yet. I'll try to get a completed pic tomorrow morning once it's light out again. That would actually be better than the one I took an hour ago.
