Ken's right, Steve.  For dialing in your oscillators and for learning 
a good deal about the sounds and control voltages, a "so last week" 
oscilloscope of good quality will work fine.  Check out the local 
amateur radio swapmeets (I can help you there)and you'll find the big 
names (HP, B+K, Tektronix, etc...)going for pennies on the dollar.  
My most expensive 'scope cost $125- 50MHz B+K.  I knew the seller and 
tried before I bought.

I don't know If I'd even want an LED based 'scope, Ken...I LIKE a 
pretty picture!

Chub-'scoped and ready!
