+1 for the SM7b. I’ve had it for several years and love it as a vocal mic, and it seems to do well with whatever I throw at it. I don’t have a CL-1, I might take a look at one of those. Do you use it live or just when recording?
There are some “cheap” condensers that are really impressive for specific uses, but they don’t have near the flexibility or durability of the SM7.
Regarding software, there are good packages at any price point. I use (and like) Reaper.
