mini starters for a 1966 273 header install

I am in the process of installing headers on my 66 barracuda with a 273. My options seem pretty limited.

TTI recommended using the Mini Starter (item # 123-1000) from 440source. I have verified that the starter can work with small and big block engines
Anybody with any experience with this starter?

I also found a Rareelectrical r53005984. Any experience with that?

What is everybody else using?

Oh, and any help on a 90 degree (right angle) oil filter adapter

thanks
