I've never understood quite why custom L-brackets are so expensive. The Leofoto is by far from being the worst offender but given you can get a generic part for less than £10 or so, it's difficult to see why a custom part is so much more.
The LPO-OM-1 is just about at the upper limit of what I was willing to pay, with the added complexity that it seems no European distributor carries it, so I had to order from the USA and take the hit on shipping, adding to the cost.
It's a little irritating that the strap loop at the left-hand end of the camera is slightly fouled by the bracket but otherwise the bracket does a great job.
