I agree with Valiantman. I also have 4 copies of Albedo 4 and I have the full run of Usagi appearances (Albedo, Critters, all UY series, etc). However, I have never given a thought to TNMT apart from Usagi appearances. I want to read Cerebus, but will do so via the phone books rather than the individual issues
A lot of collectors have been priced out of Albedo 2. The 6ish issues on ebay have been sitting for a while. As I said in a previous post, I would like to own an Albedo 2 9.8, but at $30k, that is way out of my range for that issue.
