Hello Dulciana - I have a Wyvern Sonata two manual which I bought in December - although I may not be the best advisor as I'm a beginner. Being rather ancient, I felt I'd absolutely have to have a home practice instrument in order to make any decent progress. However, I'm so delighted with the Sonata. I was a little worried about the size of the pedalboard at first, which is half size, but it's fine and I have little problem transferring to the pipe organ for lessons - the ideal instrument if there are contraints of cost and space...
