Looking for advice. Got excited when my bro told me they finally made a glass dome nail for my micro g. Saw the Halo at $45 but cheaper on eBay. Then saw Thunderdome V5 and it's almost half price,nichrome coil plus an extra coil for $26. Anyone tried either? I'm going for the Thunderdome because I know I'm going to drop it so I can use the extra cash for a replacement dome and still have change.
