I have the basic bench mate secured to my work bench. It is 25 years old and still running strong. The newer ones are make to be a little more comfortable and lighter without compromising effectiveness and will be the business. The stone setting package for the bench mate if you are using an engraving ball is not necessary as you will very rarely set stones in the bench mate. If you don’t use an engraving ball it would be a good purchase as it also comes with an inside ring clamp and full set of collets.
If you have an engraving ball the extra set of collets ( under the sub heading ring holding) is all you will need. and it will save you some cash. you place the alien key through the steel expansion wedge and into a hold in your block and use the block jaws to expand the collets.
I do have the ID ring holder and it works nicely but not so much as to justify the expense.
I have a Graver Max G8 I use a 901 QC hand piece i have a magnum hand piece but use it very infrequently. Any time i need it i find using a chasing hammer and a bunch or traditional graver works better. the point is you only need one hand piece either will do the job so choose one you will not need 2. I have a high speed air drill and it gets a workout so is worth the money. The air drill is great for notching claws and helping to cut channels and seats for regular and odd shaped stones. The fast speed and low torque gives you amazing control over material removal.
I use 4 graver shapes for 99% of my work. A 90 degree a 120 degree an onglette and a flat. The flat engraver for material removal but more often i use it for removing backs off of watches. It is perfect with a bit of air power for getting under the indent and easily getting the back off the most stubborn watch. The others for lettering stone setting and general engraving. I use bead setting punches in the quick change holders to turn beads when doing pave setting. I have a square bit of tool steel polished up and use it with the handpick for bezel setting. I have shortened miligrain tools and use them with the engraver to roll milligrain as well.
Over time i have shaped and polished a series of old beading tools to use in the handpick for texturing and backgrounding. It seams that every few weeks i am altering something to put into this bit of kit.
I use Thermo Lock as well for work holding and putting handles on files and hand gravers.
