Welder, what size screen are you interested in? Furuno has a 10" crt that is priced pretty well. Let me know and I will be happy to help. You can also email me at Barrett@southshoremarineservices.com as most of the day I will be away from the computer but will get your email on the blackberry.
If you want to stay Furuno and want standalone the only one available is the 10" crt 1832. If you go with the 1734c navnet model that is color and 4kw you can add an antenna and have a dual function if you like or just interface over from the other unit.
