I have 7 Desire Stainless Steel Rollerball kits from Lazerlinez (older model with metal threads) available as a package for $115 US, includes postage to Canada or US. I can also throw in a set of used bushings into the deal.
I'll take those. However @GoodTurns just posted he is looking for some so if he wants them he can have them as I still have a few and not a major need.
