What's the best 1992 300E Tech Manual to buy

[H. Halbuer]

I've just purchased a 1992 300E and I love it. It's just a gorgeous car inside and out. The MB mechanic at AutoEuropa in Naples, FL has just completed a valve job, new radiator job. The car is going in Fri for new fuel injectors. All of this is work beyond my scope of ability. The car has 112k miles on her. I paid $6200 for the car and when you add an additional $2600 in work, I'm into the car for almost $9 grand. To me, it's worth it. The shop says that the rest of the car looks fine.
I am looking for an excellent manual to assist me in doing simple work like changing lamps, tracing radio/antenna wiring diagrams, and simple maintenance I can do in my garage.

Which manual should I buy?
PS If anyone knows where I can buy an aftermarket fixed antenna for this car, please let me know.
