I guess that the trouble is that I'm happy with my wireless that works well 99% of the time and don't want to spend any money on something that might not be any better or could be worse.
Absolutely agree - if it isn't broken don't mess around fixing it!
If you have a reliable (and secure!) connection using wireless, and the throughput is good (or just good enough) there's absolutely no good reason to change anything.
For a new install I would consider Homeplugs and wireless together on their merits against the purpose of the install. Where wireless doesn't work I'd seriously consider homeplugs. But where wireless is working stick with it unless/until that changes.
