Welcome to PuristSPro Ben!
Hope you'll be able to find some elements on our Patek Philippe forum.
I don't know if there is such website, listing all Patek's references available on the net. Most of the work which has been trying to make an overall view of Patek's collection is mainly available in books support.
The simpler Pateks are very appealing watches indeed and carry the full Patek DNA. I think you're taking a good decision.
Concerning the period you're focusing I could find this (this may not be exhaustive), with manual or automatic movements.
Ellipse d'Or:
- 3546 (1974)
Calatrava:
- 2508, 2509, 2526, 2569, 2570, 2582 to 2594 (1958-1959)
- 3400 to 3413, 3414 to 3445 (1959-1960-1961). The latter has a beautiful and cleverly designed 27-460M caliber
- 2591, 3425, 3460 (1962)
- 3439 (1966)
Cushion shape:
- 3585 (1970)
- 3573 (1970)
I hope you'll find what your looking for and please, do not hesitate to share your findings with us 
Cheers, Mark

Ben, an excellent book is "Patek Philippe in America - Reference Guide - Volume 1 Men's Watches" by John Reardon (formerly at Patek and now Int'l Head of Christie's Watch Dep't). It pretty much covers all references (not just the less complicated). I high...

.....we are in a similar position. I also am thinking hard about buying a vintage Elipse this year...and you are correct....there are plenty of variations. By the way, welcome to the forum and good luck with your hunting. Best Joe
