Well, thanks everyone!!
I ordered the Hitachi version of the new model Tanaka trimmer that Carl recommended. I ordered on Amazon, because I still couldn't get that link to work and although it was $20 more, Amazon had free shipping and I know that if I have any problems with it(at least right away), they'll cover it.
I would have liked it to say Tanaka instead of Hitachi, but the Tanaka would have taken almost a week longer to arrive, and I'm pretty excited to start using it.
I'll be sure to update this thread after it arrives, but the quick rundown: 21.1cc, 11lbs without fuel, straight shaft with a solid driveshaft. Paid $211 after tax.
