?New electronics?

[Half scratched]

I am restoring a Santana 22. Most of the electronics on this boat have quit working. I need to replace the depth sounder the knot meter even the old compass is shot. I would appreciate any information that someone might have on a system that would be reliable yet not break the bank. I know some systems integrate. I don't really want to have multiple displays taking up room as the boat is pretty small. Any ideas.

We've been quite happy with our non-integrated signet instruments.
