been playing w/ my trv27. the laser works really well. you can buy the mini lasers at costco, lowe's or home depot. best deal costco 15$ you get a 18 inch laser level for the house plus a mini w/screwdriver attachments . two part epoxy beats the hell out of duct tape. buy two and attach one to the camera. site like you would a glock. firearm instructor once told me " It isn't the weapon, it's you." I hold it true, whate'er befall;
I feel it, when I sorrow most;
'Tis better to have loved and lost
Than never to have loved at all.
