When I had my CB42 (many years ago) I liked it a lot. Easy to use, and it made aligning a cb radio a snap. The problem is . . . now these sets are almost 40 years old. Getting a good one that doesn't have problems is a crapshoot at best. Besides, tuning up some of today's 10 meter exports with the CB42 is a stretch.
Personally, I would buy a good rf signal generator, an audio signal generator, 100 mhz freq counter, a GOOD wattmeter (like a Diawa CN-801HP), and a 100w Dummy load. I really think your money would be better spent like this. If you shop around you can find all of these pieces reasonably priced.
But if you're really set on a CB42, go for it. When it's working 100%, it's a great piece of equipment.
