Black Rapid and OP-tech are brands you can search around for Do some googling and you'll find allsorts of stuff available.
What camera do you actually have and what do you do with it?
It's all very well saying Blackrapid but if you have an Olympus Pen and shoot mostly indoors then it's overkill to say the least. If on the other hand you lug a D800 round with a 24-70 then maybe it's a good idea!
Also are you one of those weirdos that have your strap round your neck and camera bumping on your chest or someone that carries it properly over the head and shoulder and down the side/lower back?
EDIT: www.etsy.com is a good option if you have a lighter camera and don't do much hiking. Has lots of designs from independent makers.
have a look at these
http://www.qstrap.co.uk/ he is a reliable guy to deal with and the strap seems fine, a lot cheaper than black.r straps if your a tp forum member you can get a discount as well. have a look on the dealers section on there
Hope you have more luck than me!
Was just about to post and say I wouldn't touch them with a barge pole after having the connectors fail on two q straps of different designs. The guy is very reasonable but the product is cheap because it's rubbish.
