Is this the end of my GNS Collecting?

The postie brought these two books to my hands today, the first having to travel the width of the Atlantic to reach my greedy fingers:


I have been after these editions for over a year, as they are by far my favourite editions of Guy N Smith's Satan's Snowdrop and Bats out of Hell. 

 

 I don't think there are many more GNS books out there that I am actively seeking now. Could this be the end of my collection? We'll see.
