I've been looking mainly at soda blasters but I feel like I'd need something coarse to clean the cast like you did.
I tried soda but didn't like the results. I have been using glass beads for everything except the frame. I turn the pressure down to about 75-80 for aluminum and most of the steel work, but I shoot unregulated pressure for the really tough stuff. It's anywhere from 135 down to 90, where the compressor kicks back on.
I have a blast cabinet from Harbor Freight that leaks like a bad boat and it uses a syphon gun. For the frame I used really clean 70 grit sand from a brick supply place and had to use a pressurized tank system (also from Harbor Freight), outside, because the frame didn't fit in my blasting cabinet. The sand and pressure tank will strip just about anything.
I'm planning on building a bigger blast cabinet so I can do my next bike completely with glass beads, which leaves a much nicer surface, and work completely inside. Working outside really sucks!!
Bead blasting uses huge amounts of air so you really need a big compressor and if I am doing a lot of blasting I hook up a second compressor so it will keep up.
Life is short, live and enjoy it !!!
