I bought both as spares.
IF I will keep the machine longer its nice to have some spares.
IF I sell the machine I can sell the parts to the machines buyer or as single parts.
Better have, than need ... Last pin I bought is a sopranos. I needet plastics but they are not on the market anymore .. expect on ebay for 300 Dollar plus shipping, plus tax. So bought in the right time the set was 140 Dollars. With Alien parts it will be the same in some years. Maybe we have repro of this part or we will have to pay hard money.
I am looking for years for 2 wireramps from BBB .. they were at PPS years ago for 80 bucks .. now its no chance to get even one for 300 dollars.
So far I collected:
1 x pc working and comüplete
1 x I/O board
1 x power Board
2 x facehugger original
2 x facehugger repro
16 x LED remake
Coming soon .... slingshot pcbs ...
Targets and reed-contacts would fit fine in this collection ...
