apexi isn't bankrupt. they're still carrying out business as usual. some smart sellers have used this excuse to bump up prices.
Apexi did reshuffle their powerFC lineup though. They relegated units for engines that were 10 years out of production to the Apex Engineering line, and only kept the ones newer than 10 years (hence RB26, SR20, RB25 Neo) in stock and available off the shelf. The older units are still available, but as special order at minimal extra cost.
just cos your agent can't be arsed putting in that order and then getting it to you, does not mean that it's not available or should be much more expensive.
