Personally I would advocate joining a syndicate anyhow - if only for a couple of years, as you'll learn so much from "those who have gone before", and then after a couple of years, if sole ownership is still your aspiration, you'll be massively better placed to pursue it intelligently.
I've been flying for 30 years, both SEP and microlights (both flavours) and have universally found the syndicate experience much more satisfying for me than sole ownership.
