Looking at selling my nevilles but really have no idea on what i should ask for them. can someone help with a valuation?

2 x steve neville remote alarms with silent function - Double white LEDS on both
1 remote - All Blue LED The older type

2 x matrix speaker bungs

2 x white roller wheels 2 magnet
2 x white roller wheels 4 magnet
2 x black roller wheels 4 magnet

4 x black jag snag ears (Left and right for both alarms)


2 cotworld aquarious fabric alarm covers

alarms are in excellent condition apart from a couple of line indent markings just behind where the roller wheel sits


Cheers
