Well, we're going to have plenty of time to find a solution to raise the $3500 for the tooling, since TJ won't be running this until probably June.
My suggestion would be to combine DSA Orange Crush with two other DSA sets into one big GB. Use Matt3o's GB software for orders. Run it in the usual GB timeline, not flash, not R4. That way there should be more orders to spread the cost of the tooling, and everyone pays less subsidy, as in 7bit's R4.
I was thinking that the sets that would get the most orders, if run at the same time as DSA Orange Crush, are Matt3o/samwisekoi's DSA Retro Blue, DSA "R4-Retro," and DSA "Round 3" style.
Or TJ could split off Orange Crush (I've used it 3 times now, TJ, so this is officially the new name), and run it through GMK, while someone else could run the DSA sets GB.
