AstroSystems Autocollimator - 1.25" or 2"

As I'm waiting for a delivery (3-4 weeks) from Astrosystems I would like to add to my parcel an Autocollimator, but can't choose which one.

My choice is between the 1.25" Autocollimator at $45 or the 2" for $89. What are the practical benefits if any for choosing the 2".
I have noticed the "Catseye" people don't do a 1.25" but do recommend the Astrosystems 1.25" for those who want one.

I have read that the autocollimator is far more accurate than any laser as it uses multiple reflections. Now as most focusers have some sort of slop when fitting any tool to it, will this same slop have the same detrimental effect on the autocollimator as it does on the laser.
As the autocollimator is far more accurate will this slop have less negative effect on the final setting.

Thanks
Richard
