VigilanteTrail Me.....I would not invest money in something like that. Just do it the old fashioned way. Would take forever to recover the cost of such things, even when it may be fairly reasonably priced.
In this area, you can get grips installed for $2. Not sure what GG charges though, may be as much as $5, and that's no profit for them.
Just checked.....GG charges $3.99/grip.
