I think some of the more newer members may be better to answer this question overall for relating to you and your situation. I, and some of the other long timers watched the pen plethora develop from 20 to 30 pen styles into the explosion that it is today. Since I have this bit of background knowledge, I do go to websites about once every 3 to 4 months and just spend an hour or so looking at the pen styles. And since I have a a long background and know numerous pens, I can skip over reading about many.
That does not work for you, though. One thing that I have done and do now on occasion is that I have a database type of app in which I do a copy and paste of both information, web link and picture of the ones I like. And on occasion, when another style comes out that is very similar to a previous one, I may copy/paste the new one into the page with the similar one - which helps with reference as to which company has which pen. I have been doing this off and on for about 15 years now. For much of my database, it is taken from posts here on this site by individuals that make exceptional work. (Many New turners are as good as some old timers too.) It is great to go back and look through on occasion and find who has what, and how it looks through creative eyes of pen turners here.
I do agree with you that a catalog is so much more helpful.
One thing to look for in your search is the quality of pens. Many pens will look the same but the quality is different from different companies. Usually it is reflected in the price.
