I would love to play more MTTs, but I just don't have the time.

There are now some multi-table SNGs being offered on pokerroom.com (where I play cuz its Mac compatible) - but the payouts are more concentrated. A 2 table SNG pays the top 4, a 3 table SNG pays the top 5 - so if you finish ITM, you get a pretty good payout, but its harder to finish ITM.
