Hmm, unfortunately you’ll have to wait awhile for another to pop up on eBay, which is kinda unpredictable. For the time being, I’d suggest something smaller and easier to own first before jumping into fixtures like M-400s due to cost and availability.
Just a heads up: I know kcbhiw1, no he is not a hacker.
I know it's an old thread, but does kcbhiw1 still have any for sale??
