Add to that that by the time you get a new Hyperstar in your hands, between the exchange rate and GST and freight you will spend two thirds of the price of a RASA 8.
If a Hyperstar for my CPC925 came up secondhand at a good price I would be tempted, but if I wanted F2 new, I think I would just go buy a RASA.

Ah yes, the collimation would become quite a drag! Thanks for that reminder
