Andrews has the Cheshires for $29 a pop. I know cos I just ordered one. To save further delays just include one with your order. (No I don't work for him.
...and iceinspace.com.au is not a subsidiary of Andrews Comm.
)
PS. I've had my scope for 6 months and it took me that long (along with some $$ spent on the wrong things) to learn the information contained in this single thread.
