I've used various scopes over the years and when I went on my own about 8 years ago, bought a used analog scope. It worked OK, but when it got down to needing even simple logic analysis, it didn't hack it. At that time I bought a BitScope - low cost (used the PC for a display) and had analog and logic inputs.

It worked OK until one time I needed to 'see' the analog based on a logic trigger. That model just couldn't do it. I recently bought a Rigol DS1052D which has 2 analog channels and 16 logic inputs. It was a little pricey ($1000, I think) but it has done everything I needed.

If cost were not a factor, I'd go for one of the newer Tektronix scopes that include protocol analysis. But, if cost were not a factor, I'd probably not need a scope!
