A relay similar to the one I used, but with the timing adjustment on the relay itself, is available used on Ebay for $62 + ship. See also the 'also viewed' other P&B timing relays.

For what it's worth, should anyone else be pursuing this, the strength of a solenoid may be rated in Newtons. A newton is equivalent (I think) to a 1/4 pound or 4 oz. While a force of about that much or a little more may trigger your shutter, it will be slowed by developing that maxiimum force (if that is all your solenoid is good for). A force of around a pound or 4N would be better
+1, I'll be happy to beta test one
