I've seen them every now and then from $3000 to $4000 so that's the route I've chosen to go if I can find one for say around $3500. I have a 96 114TC N295TC and currently have a KLN-90B and two KX-165 so thought I could pull the KLN-90B and install a 400W and not have to butcher my very nice factory panel as the 400W will fit right where the KLN currently sits, then I could sell my KLN-90B for about $800.00 to $1100.00 which then puts me only about $2500 into a400W. So this is kind of why I'm leaning towards a 400W.
