What type of fishing do you do? It all depends on what your budget is. If you are looking in the $300 range and want color, it is a great unit because it has color, temp, a flasher and regualr graph mode. If you do not need color but still want a $300 or so unit. I suggest the Lowrance X125. This unit has 2400 watts of power and 480×480 pixel display. I believe this unit goes around $299.00. Jolly Ann Marine has no sales tax or shipping if you live outside of Iowa. Here is the unit @ Jolly Ann

I have a Lowrance X67c plus (speed and temp), that is in getting repaired. I only had this installed on my boat for one Summer. It is only like 2 years old, not sure what is wrong with it yet. I will be looking to sell this unit once I get it back for I have upgraded. I will be looking for $200 (paid $339.00 with speed sensor) when I sell it. I just need to check back in with 2 other people before I could sell it to you. I had it sold before but when I took it off my boat, it did not work. I just need to make sure he still does not want it.
Hope this helps!
