Perry Rhodan?

[Power Man]

Yes I remember the PR series. The paperback books started out at 50 cents each. Still it was a lot for a young kid in the 70's. I would vist the bookstore and bring back 2 or three new one each visit. I recall coming home once and sitting down on the couch and not looking up till I had read the whole book.
There are LOTS of ships described from small one man scouts to planet size super dreadnoughts. Lots of various beams and missiles too.
I remember massive battles with 1000's of ships on each side.
The story line went from book to book with each one ending in a cliff hanger.
I may even still have some of the books in an old bookcase.
