Best x-crossover under 500

Yes I do have a tread on x-overs on another page. But what is the best x-crossover for a sub under $500 new, I say new cause its probably hard to find a good used one.
The HSU out board x-over is excellent. Be careful if you order one to make sure you specify no low pass EQ and pick the correct corner point for the subsonic filter. Also, a Marchand XM-9 deluxe two way is an exceptional value and right around $500, cheaper if you build the easy kit. Good luck
i use the marchand xm-9 deluxe, & i tink it's a great walue - wery flexible & wery transparent.
