Welcome to The Router Forums!
With regards to your current router and or table, my thoughts run parallel to those of Otis.
In my opinion, Ryobi products generally offer a tremendous amount of bang for the buck in situations where starting out with 'top of the line' isn't required AND you are willing to upgrade to higher quality machines when the need arises.
Considering your reference to older tools, I think you might be familiar with winding sticks. They come in handy when checking the flatness of any board, whether it is a router table or not.
By using your current setup to try things out that it can do and documenting those things you would like to do that are beyond it's abilities, you can gain 'solid ground' on defining what things make a difference to you when selecting or designing it's replacements. You may come to decide it's all you need, and you may grow out of it.
To expand a little on the theme of practice, I would add that most of my tinkering around while getting to know my router has been on hem-fir 2x4 stock and/or cedar fence boards. I have been doing my 'hardwood' practicing with 'flooring samples' from my local Lowe's.
Thanks for joining the group!
