I still have a few leftover DIYino Primes, mainly repaired boards I salvaged from earlier, sold out runs.
The Prime is currently the only LS saber core on the market, and IMHO the best, since it was developed by an LS enthusiast for other LS enthusiasts.
But here also a certain haste is recommended, since I'm promoting the Stardust currently, I do not foresee any Prime restock in the near future.
