There is a colour Lowrance x107 df sounder for sale on the ausfish classifieds at present.

Worth around $1000 new 2-3 years back. I would go that over a new monochrome sounder any day.

If that doesn't suit, look on ebay. I picked up my Furuno FCV600L colour sounder for about $600. Very happy with it.
