I used a pair of Solen 47uF @ 250 volt caps in parallel. I simply rounded up to 100uF nominal value in my post.

A less expensive alternate are AeroVox polyproplyene 35uF motor run caps in those grey plastic cases. Common value are 35uF @ 250 volts. I find them on eBay for about $3 each or less in larger lots. Use three in parallel if chassis room is available.
