Looking for a new borescope without spending too much money. The Snap on BK6000 with the BK5500-12 dual imager would be great. Was wondering if there were any cheaper options out there that don't have clip on attachments that easily fall of. Ideally, I need one with a straight view and a right angle view (45 degree mirror). This is were the cheap attachemnts that fall off are a problem. Ideas?
