IslandRunner - I bought all my starboard from Cesany Plastics through his
ebay page (free shipping). Was by far the cheapest price I could find on starboard, and he cuts it to your desired size for free! I have the HDS-5x so I can have full time chartplotter with all the radar information/sea surface temp/winds/etc on it and then also have a full time bottom machine. The HDS-5s are really too small to do split screen on, you can do it, but to me its just too small. Plus I got that unit used 1 year old from a charter captain in NC with everything that came with it in the original packaging, the price was right.
