Ikelite DS-51 vs. S&S YS-27 DX

I have a Canon A710 IS w/ an Ikelite housing. Base on my needs and budget I'm looking hard at these 2 strobe systems. Anyone have any thoughts on the relative merits of these 2?

Thanks!

The DS51 has a bulkhead connection so that you can connect a sync cord. That may be useful if you upgrade to a different camera later that uses sync cords.
