Hotchkis TVS worth it?

so ive seen articles in my mopar magazines an saw a video advertising Hotchkis Total Vehicle System (TVS). has anyone here used the system? i dont know very much about suspension upgrades and what it should cost but this kit for my 70 dartwould run me around $2,300. is that alot for a full vehicle suspension upgrade? i would lovge for my car to handle better and this system seems promising. just curious
