It's almost never as cheap as you think it will be. Of course you could also just call Paul up and buy a Rick Engman rebuilt Renesis engine for around $2K or so. That's probably the same that you'd end up spending anyways but with the peace of mind that it's built properly!
The invoice reads like this (I'm too lazy to type out part #s):
Rotor kit $1378
Gasket set $252
Gasket set $118
Oil seal front main $11
Oil seal rear main $9
Front housing $394
Rotor housing $563
Rotor housing $565 (different company, shortage in the country at the time)
Mazdatrix and Mazmart were great to deal with for the parts.
And of course Charles did a wonderful job on the rebuild:

I spent $3,400 on just parts, including new housings, seals, etc.

Do you think the front iron crack has something to do with the housing? cuz I know that Rx-7 S4 had this problem too --- crack at the dowel pin area --- they fixed it in S5. Dont think current Renesis has that extra reinforcement.
2nd time seeing this video, still nice

strength is no match for the unbendable arm!!!!!!
I want to learn how to build this engine--recip knowledge helps some (bearings and such) but in getting the rotors balanced out better, proper seals, port mods is where i have the most to learn about. I know just enough to be dangerous.

The how-to part is the easiest one with this engine in my opinion. The problem is transferring that knowledge into the build
I mean, putting the parts together is something a trained monkey could easily do, really.
My own concerns as a common dude are: balancing everything for precision builds. That kind of machinery is freaking expensive, you need a job to do that. Not 100% necessary but you mentioned it. Same applies for the bearings.
Then there is the clearancing part. Just as important and is mostly a matter of the right sand paper with the right tricks (side seals DO wear, right clearancing does help ).
Port mods is a pity with our engine. You either go big and bridgeport it (again, talking about machinery) or all you can do is playing a bit with the intake ports and even less with the exhaust ones.
Charles and rotarygod were so kind back in the day to help me with that. The thing is that it is not just about dremelling the ports, you need to slightly rework the intake ones for better flow. Flowbench = expensive.
Oil ducts etc are a bit easier to do imho and need no explanation other than the pics you can find around here.
All in all it can be done. Will it last? Depends on you (skills, tool bag, patience ad budget).
I started working in my balcony slowly buying the tools i needed. The first rebuild took me around 5 months to complete in my balcony and was a 400 hundred mile engine from a crashed car. Now it takes me around 10hrs the rebuild itself, the whole extraction-installation of the engine is something i can't do at the moment here.
Pay attention when you clearance the side seals, and when you clean the rotors. That carbon power sticks to your clothes. I am pale white but i remember looking kinda tanned after the first try
I hope this helps.

ps
Paul are you so serious about training at the gym? We might to a "rotaryheads" shootout

that's a quick fix.
I think I've got a DIY on that.
