The following was reply to an email I sent to Mighty Mike last Xmas. He's been selling them for a while on Market Place.
If you have a camera already the clock is on a K mount that you just push in.

Hello Honey Bo Bo,
The total for the ME with clock inside shipped and paid by Interac E-transfer is $75 CAD. The total for just the cap with a clock and paid by Interac E-transfer is $45 CAD. If you require Paypal then the totals are $78 and $47 respectively.
If you're ready to buy in either case my email address is
mighty_mike88@hotmail.com
Thanks
