not sure if 'lifting them' is a good idea.
I have sourced them from a couple of places.
1. NZ. there was a NZ based DIYCer who had 100s of them, I bought a carton of them
2. Chris was selling them via his website .http://radiant-holidays.com/radiant_holidays/index.php?main_page=index&cPath=1
3. Optus Techs have been known to loose a couple off the truck, a slab helps.
4. RF Store (?) in Australia was stocking the CG1500s
