I prefer the dunlop system but aesthetically its a bit cr@p, it sticks out quite far compared to the schaller. On some guitars i have used the flush mount dunlops which are much better but obviously it means you have no standard strap buttons so you had better not loose the strap with the locking bits on.
Oh yeah, if your a gigging musician you should have a bag that you take to gigs (called a gig bag

) with things like spare leads, strings, batteries, gaffer tape (always comes in handy!!) and a few tools including an ADJUSTABLE SPANNER.
