I bought the Chirp 93sv off eBay New for $740. For a 9" side vu unit you can't beat it for the price. I think the 2D is one of the best on the market. I think the down vu is great too. So far, I'm still working with the side vu. I use it to find cover and brushpiles and less for trying to spot individual fish, and for that it is wonderful. If you rank the high end bird and lowrance birds at a 10 then I would say the Garmin is a 9. So you can decide if that one point is worth the extra money.
