It's a late reply, but wanted to give "thumbs up" to the Perfect Viewer suggestion. Most any android device (and I've had several) seem to work very well with Perfect Viewer, though of course I'd recommend a minimum of a 7" tablet to prevent eye strain.
By fortunate circumstance, most of the old comics work extremely well in the wide format, showing the top, then middle, and bottom of each page at close to the original size with each tap in the proper place.
Also of great use is the network feature in Perfect viewer. Rather than loading comics onto your android device, just access your computer or external hard drive through Perfect Viewer's LAN feature. You might have to use another program like Explorer ES to determine the correct local IP path. Perfect Viewer seems to work quite well with most files of up to 40 MB; you might experience slow response or crashes with larger (60MB) files, but this is usually only through the LAN option. If you're accessing files loading onto your device, you will have less hassle.
Since color Nooks now have Google Play, Perfect Viewer is available as a free and an paid app.
