Your second question (in the form of a changed subject) makes me
wonder if your original subjectquestion will be meaningfully
answered...

Where do you live? (country, region...)
Do you have any pilot ratings?

Answering this will allow people to make reasonable suggestions to you
for getting gliding lessons if you are actually looking into training
options. From your question though, it would seem that worrying about
which motorglider to buy might be a little premature at this stage...
not that I discourage dreaming ahead
