Juniper list price for 1GB of CF is around 100 times what I would expect to pay for a third party card.
The J-Series release notes have a list of supported third party parts, but there is no equivalent list for the M-Series.
J-Series Supported 3rd party hardware
My questions are:
Does anyone have any experiences (good or bad) about using 3rd party flash in an M-Series routing engine?
Should anything on the J-Series supported list work?
Has anyone had JTAC refuse to support a problem on a router with 3rd party flash installed?

I have found the following page which states that, with caveats, off the shelf SanDisk cards should work.

It looks like modern, high throughput, cards could cause issues though. I am still interested in hearing anyone else's experiences.
