Only thing I can add about starters is if you buy a quality Sullivan starter, you won't need another for many many years. A sullivan is the only thing I can get to crank over my OS .91 SZ-H Hyper w60M-C Carb! I also have Ace and a Hobbico starters. They are good up to .60 size, but they won't thump over the .91!
Spend the money for a Sullivan if you can afford it. They are worth the money. Also from what I've seen at the field this past year, the guys who bought the geared sub-C powered starters have all gone back to regular starters. They just didn't hold up very well and are VERY noisy.
My 2 cents worth...
