Welcome Alex.
You can keep an eye on the For Sale, Seen on eBay, etc thread, or list your desired bass in the Wanting, Wishing, and Watching page. These are all inside of the Swap Shop and Wish Lists category.
Members sell instruments on these pages sometimes, and it is not uncommon to see Spoilers being sold on this board and at eBay frequently.
Welcome to the club, and I hope you have some fun finding and buying your Spoiler Bass. If you need any help, please ask and lots of members will be happy to help you here. Most importantly have fun!
If you are not familar with dealing on eBay, please be careful there. Ask everyone lots of questions before you buy or bid there!
