Patch sources
Where can you get these fancy patches?

eBay
Web: www.ebay.com

Ebay is one of the best places to look for space-related patches and find fellow collectors. Takes some experience to filter out the bad deals, but every now and then you'll find a patch that makes your heart jump. Only disadvantage: prices go up really fast if more people are interested.
