Stick with your Steelfish. The steelfish is no longer produced.. and hard to come by. You can get the Ultimate "V6" DSSD from Lay for $88.00 with 21j. It's a steal, and has the same case and crystal as the more expensive version. If you decide you really like it. pop for the ETA version for about $250 from trevor and you're set.
In any case.. I wouldn't get rid of your first and only Steelfish rep to get a DSSD. I have both and LOVE both equally. In fact, I wear the DSSD considerably more lately, but both are EXCELLENT watches.
@Ronin: Someone has joked to you about the "Gas Escape Valve" on your DSSD? I get the joke, but just can't see any serious person cracking a joke at something so contrived... I mean honestly.. this person must crack up everytime someone says I need to fill up my Tank with Gas. Or a Gas Powered Furnace...
I mean seriously??
