I have the HB 788ci and really like, I think the msrp is $649. The hb 587ci and 597ci $469 and $569 in color, the color helps out on the maps because you can change the color on the depth's. I would also get the Navionic's hot map chip it's a real help on the bigger lake's with the hi-def chart's, but I don't think Cedar or Herrington are on the hi-def list. They just added Nolin,rough,green,t-ville and my son just told me is a hi-def lake also. The depth contour's are in 2 ft increment's. hope this help's.
