We've got quite a few Jelly and Bean. I don't find them particularly interesting, but the children are enjoying them. There are plenty of books at different levels, and I like the progression. I love Songbirds - the purple ones are only CVC words (not even "the"), but still tell nice little stories and have attractive pictures. I just wish there were more. I've also got some Big Cat phonics (good, but even fewer books than Songbirds) and ReadWriteInc Phonics (also good). If you are getting Songbirds or RWI, then check the bookpeople website - I got mine from there and they were much much cheaper than anywhere else. They've also got come Collins Big Cat books, but NOT the decodable phonic ones.
