I would have to say that it would be a good idea for someone to start off with visuals first such as pastels, spiders, enchis, Mojos, etc...
Personally, I'm a huge fan of things like the Lemon Pastel, Cinnamons, lessers, Phantoms, and Spectors. There are so many choices, that's one of the things I love about this crazy hobby of ours!
I think that the best mid priced morph right now is a banana/coral glow - hands down. They are just breath taking. I just got one for a great price and I have not been able to take my eyes off of him. They have dropped in price significantly but that does not change their beauty. In fact it allows more of us to own these once extremely expensive animals. Just my .02
