I can reel some off the top of my head
Motherease
Ecobaby
Muttaqin
Cuddlebuns
SnoogieSnaps
Wonderoos (pocket)
Pinhead
SOS
I actually have all of those in the stash
I was really trying to load up on 1sz diapers. Seems like the list was longer. For the most part I prefer 2sz systems, although I really like the fit of muttaqins, cuddlebuns, pinheads and SOS (in no particular order). I like the wonderoo for my petite 5yo bedwetter (didn't like it so much on the baby...cdn't really get the fit right).
That doesn't answer the $$ question for you, but it gives a list to start with.
