Need more info/pointless thread without details.
What do you mean high end a $20 strap is fine. Unless of course your doing some crazy guitar spins so no.
invest in lock straps(I think that's what they are called).
Strap locks are great. I have them on all of the guitars that I play outside my house.
If your spending enough money on a guitar strap to call it an investment your doing something wrong!
^Yeah, it's worth getting a good strap, that doesn't mean you pay $200 for it.
if by "investing" you mean purchasing a designer strap, something that is custom made and one-of-a-kind, than that is your choice. most good-quality straps shouldnt be much over $80 USD. i'm using the levy's boot leather strap, and it is extremely comfortable and durable, which is why i bought it.
i use the 10 bucks nylon ones (levy's and ernie ball) and they never failed me, and i like the feeling of nylon against my shirt, so i'm keeping them
I use cheapest I can find, as long as it holds my guitar with the strap locks, should be fine lol.
