There's a lot of good information and reviews of avionics at

You shouldn't disregard the installed avionics when shopping for an aircraft. It is one of major considerations as to the value of the plane. It's not just the value of the equipment but the cost of installation that needs to considered. You might see an inexpensive radio on ebay only to find out the installation cost far exceeds what you pay for the box. It's better to find an airplane equipped the way you want it than to find one with the intention of adding the equipment later. This same philosophy carries on to everything--unless you're an A&P or avionics tech, fixer-uppers always end up costing more than you thought.
