Ahoy!!

I have been thinking recently about how certain modules, that were once de rigour (at least for me and a few folk) are slipping away from us and are no longer available!

The Harvestman modules were the ones that first alerted me to this growing phenomenon, but since I have come aware of it, there are more... Make Noise - Mysteron, marked as retired on the MN website and only one or two instances in the wild that are for sale! I mean wow... what a a module, what a sound... is there anything else quite like it? I can't think of anything! It is by any reasonable definition of the word, dare I say it? Rare?

Can you think of other modules that are becoming rarities?

I was thinking of selling my Mysteron, for 'rack space reasons' it's been in it's box for a little while, but having realised that there might come a day in the not too distant future where it might not be easily replaced, or that I could end up with an instance that has been erm... lets say 'used' ... now I think I am going to keep it! It's mint!

Thoughts? Ideas? Concerns? What are you thinking?
