+1 to bubbatime, Trufuel is excellent. Minimal mess, easy transport, long shelf life. Great for a single 2-cycle household.
If you have more than one engine to power (chainsaws, blowers, et al) consider getting a simple 1 or 2.5gal gas can. I just picked up some new ones at a garage sale for $1/ea. Cheap 2-cycle oil is available ready to dump in, no guessing or measuring needed. You're looking at a few bucks a year for typical homeowner usage. Remember to factor in the cost of the HD30 you're going to put in before you try it. Modern engines do not tolerate too much or too little oil well at all, let alone the wrong type. You can look forward to a scarred cylinder, plugged carb or exhaust, fouled plugs. It's just not worth it.
I'm lucky enough to live by a station that sells non-ethanol premium fuel. I highly recommend that as well if available. We're talking pennies more per year to keep you and your trimmer's carb happy.
