What tools/saws for beginner? Overwhelmed!

Hi everyone! First post here. I've been collecting rocks for nearly 40 years (since I was a kid). Never tumbled, cut or polished anything. The last year or so my wife and I have been collecting with more purpose and want to start cutting and polishing. We don't intend to make jewlrey at this point. We have a few hundred pounds of mostly agates, petrified wood, Jasper and quartz. We also have about 40 or so thundereggs collected recently and when I was a kid. The biggest egg us around 8" or so.

We are interested in tumbling, shaping and slabbing.

I'm sure the vast majority of our stones are not tumble worthy and the pieces that are golf ball size or larger would need some work to become tumble worthy or pits cracks.

I've been researching what saws/tools I would need to get going. It seems never ending! I've read threads on dremels, tile saws, slab saws, trim saws, vib & rotary tumblers, flat lap polisher, cabbing machines, belt Sanders, grinders etc.

It appears there are hundreds of ways people shape and polish their stones.

Most posts suggest beginners join their local clubs and use the tools available and then decide. Unfortunately with this covid stuff that's a bit difficult. Though I do intend to join my local club.

I've pretty much settled on a vib tumbler over rotary as the speed is most important for me. I also like natural shaping.

I'm not looking for suggestions on what to get for basic cutting and shaping stones and then polishing. I know this sub is for cutting but thought it applied most to my questions since there are so many ways to cut.

I'm very mechanically inclined and could make the DIY machines people often mention, but I have little desire to spend my time doing that unless it makes a substantially better machine than commercially made.

As for cost, I'm value oriented but don't have a budget. I don't need to spend $5k when a $1k machine will perform nearly as well and last nearly as long.

Aside from my 40 thundereggs, I don't anticipate cutting lots of thundereggs in the future. I think the largest pieces of agate I'd cut would be 6-8".

I would also like to shape and polish off shaped concave/convex stones so assume that would need a Dremel?

What would you recommend to get going? I'd love a huge shop and to buy every type of cutting and polishing tool there is, but I don't have that shop yet!

I tried to be as thorough as I could in my needs described above. If you have any questions or need clarification, please ask away.

Thanks!
