Competitive Spreads at JMI Brokers, Yet Offshore Regulation Raises Concerns

I've been checking out JMI Brokers, and they've got a bunch of financial instruments and different account types with some pretty competitive spreads. The fact that they use MetaTrader 4 is cool and all, making the trading experience better. But I gotta say, I'm a bit skeptical because they're offshore regulated. Also, there's not much in the way of educational resources, and I couldn't find detailed info on customer support and stock trading commissions. Makes me a little uneasy, you know?
