I actually made a spread sheet over the winter comparing TVS vs RMS. You are right it's hard to compare the two because RMS is more complete than the base TVS. RMS front and rear, about $6300.00

Base TVS w/new rear shackles from Summit (2559), then go over to firmfeel for shocks (400), 1.06 Tbars (325) , bigger tierod sleeves (225), sector support kit (135),stage whatever box (330), fast ratio idler and pitman (285).. still under 4300.

As Dan said, the hotchkis website prices are what they are. Much better prices can be found at Summit or Amazon. I was able to pick up the TVS rear springs for my charger for $385 with free shipping from amazon in May 2012
