Replacement for KEF 104/2s

I have a pair of Kef 104/2s, which I have loved for years. However, lately I have been having problems. I have replaced a total of three tweeters and now I think that one of the mids is out. I think that I may have a bad crossover. Kef still has all the parts except the grills. I intend to have it fixed and then sell them. My question is, How much do I have to spend to get a modern equivalant of these speakers? If you have any suggestions on replacements it would be greatly appreciated.

My system is as follows:

Conrad Johnson PV-11 Preamp with Phono
Musical Design D-150B Signature Amp 150 watts per side
Musical Design CD-2 Signature CD player
Denon DP-60L turntable with Denon cartridge.
Kimber and Wireworld speaker cables
Nordost interconnects
Wireword AC power cords

Thanks
