[sdiy] How available are these parts to you?

[laxt57 at aol.com]

 Hi Ray
 My take on this
 1. LM3080  =  CA3080? Right?
 2. CA3080  =  2 I have a stash but don't use this device for
                      any new projects
 3. CA3280  =  2 About the same as above, This is a shame.
 4. LM13600 = 1 Don't have any, don't know any good source.
 5. LM13700 = 8 or maybe 9 Not a problem as of now
 6. DIY         = Not a problem with thru-hole, I am struggling with SMD
                       I am not so young, my vision not so good and I need to
                       buy a stereo microscope

How hard do people perceive getting these parts to be on a scale of 1 to 10. With 1 being hard/expensive to 10 being easy/not-as-expensive. I'm working on something new and I want to make it so that the parts are as available as possible. 
 
1) LM3080 
2) CA3080 
3) CA3280 
4) LM13600 
5) LM13700 
6) Roll your own simple transconductance amp with transistors/op amps. 
 
Any feedback appreciated... 
 
Thanks
