cash,
Like you, I went from equities and am now SIMming futures. Try it you'll like it. I tried OpenECry (2 week trial), they have a fast and clean platform. I just wish they offered a longer trial. Charting was OK.
Now, I am using Amp Futures with Ninja Trader (30 day trial). Again, it's very fast and a bit more robust. You could definitely trade off their charts IMO.
If you do ever get around to giving futures a try, concentrate on capturing points rather than currency.
