you wont touch a good Stihl for that kind of money... you may be able to get one for that price used from a shop that repairs and sells them tho... there is nothing wrong with Echo, BUT, you have to spend money with them as well, their cheap a$$ bent shaft trimmers are garbage, and the straight shaft ones with enough CCs and power in the motor will push you past 200 bucks...

Shindawa is another good brand, but again, you wont touch a new one for probably under 400 bucks, so you may be able to purchase a used one as stated above...

for daily use applications you will want to go with the above mentioned brands, and if Red Max is making them, they are another good one... for home use, cheaper models will last you a long time if you take care of them... i had a Ryobi that was pretty cheap, but it had power, worked, and lasted nearly 10 years... my replacement was a Poulon Pro Link, Poulon is made by Husqvarna, and they are under 200 dollars...the Pro-Link attachment system is great too, you can get attachments from Tillers to Blowers... mine has a 33cc engine, and is extremely powerfull, even compared to 400 dollar Stihls and Echos, and mine was about 130 bucks if i remember right... the head however, isnt your typical head, its a single string head, but is big time heavy duty.. mine allows me to run thicker line, .105 i can max the engine out and blast through stuff no problem, and can go even higher if i wanted to...

if you want high end, buy used, go to pawn shops and or repair shops, or go to Walmart or anywhere else that sells Poulon, and stay away from curved shaft trimmers, straight shaft ones are easier to work with, and easier to work on in case of something bad happening... plus you can get the link attachments and trim your bushes or till your garden without buying a 1500 dollar Rototiller....
