Yes I see that you ruled out butters and pastels
HOWEVER in my opinion you cannot beat a queen bee.

You can get a hatchling pastel butter or pastel lesser and offspring wise you will be golden
bumblebee's
queenbee's
butter spiders are attractive.

And yes still going against your post another stunning combo

lemonblast (pastel pinstripe)
another wicked combo to pair with the spider

If I was in your shoes and sticking to 2 bp's with your price range and working with the spider gene definatly a pastel lesser! if you look around fauna you can get them for about 225 shipped or + shipping

just my 2 cents!
