Hi Mary Anna & welcome to MR.
Difficult choice you have to make. So many variables. Have you checked the
wiki yet? And have a look through the '
Which one should I buy' forum. It might give you some ideas.
Once you have narrowed it down or have more questions, please ask. Lots of nice people here willing to help.
Oh, and as a writer yourself - hop over to the
Writer's Corner and meet some fellow authors hanging out here.
