76csx also has USB. I *think* it's the only model discussed in this thread with both. Not sure about the 60csx. Amazingly, I know some folks who use old computers, fish finders, chart plotters, etc who consider RS232 a useful feature. That's why any used 76csx is more likely to sell to a boater than a geocacher.
Happens a lot. Scared another newbie off, all this intensity here
Or maybe he's just watching that original auction - it's at $43 right now. And in the context of the original question - yes, at a good price the 76csx would be a good beginner's choice. Obviously the market at large values it more than your limit of $30, and I myself wouldn't go over $80 for it.
Academic, that is. I'm not in the market for one right now.
I've been watching quietly from the sidelines
Based upon these replies I think I'll skip this one and go for a paperless model. I appreciate the comment. Cheers
