I have often identified the Incredible Hulk as "my first favorite character" but I don't think I've ever mentioned that Captain America is "my second favorite character" (in sequence, not in rank). I think I probably started collecting Captain America for good and all when Hulk #231 crossed over into Captain America #230. A friend of mine had a beat up copy of Captain America #227, and this was right around the time someone sold his comic book collection to the Armchair Adventurer bookstore and I was able to fill in most issues from #114 through Kirby's mid-70s return in one swell foop. I didn't take too much effort at that point to fill in the issues I had missed from #215-229. In any case, all these things happened right around the same time to the best of my recollection, and I continued to buy every issue of Captain America for many years to come.
I was lucky enough to have bought the Stern/Byrne run in "real time" and I was on hand for the DeMatteis/Zeck/Beatty run shortly after that. Unfortunately, those two runs were not a one-two punch; more like a one-two punch with a feint between. I prefer re-reading comics in collected editions on good paper stock rather than pulling my originals out of their boxes if at all possible. The good news is: Marvel has a great line of "Epic Collections." The bad news is: I didn't find the Captain America Epic Collection Volume 9 (reprinting #247-266 and an annual) to be a particularly good buy for me.
First of all, the DeMatteis/Zeck/Beatty team took a while to coalesce and gel. Second, the Stern/Byrne run has been collected an reprinted so often I really don't have any need to own it again. Third, between the two runs was a series of fill-ins. The DeMatteis/Zeck/Beatty run didn't really kick into high gear until #267. the best news is that the Captain America Epic Collection Volume 10 collects #267-285 (plus an annual and a crossover), the very height of the run. I've got a ton of trade credit built up at my LCS, but I was waiting until the release of v10 to get both.
The only (slightly) disappointing aspect concerning v10 is that the cover of #280 (which depicts Cap beaten and in chains) was chosen as the cover of the collection. Better choices would have been #275 (Cap in full-on action mode leaping directly at the reader) or #284 (Cap on a rooftop with the American Flag below him, flapping in the breeze).
Although it hasn't been just too long since I last read the Stern/Byrne run, approximately five years A.T. (i.e., after moving to Texas) as I like to say, when I return I plan to begin this discussion with issue #247.
