Don't bother with the Poulan.
I run Stihl, Husky, and Echo chainsaws regularly. Based on that experience, I started buying all Echo for my other equipment. The Echos just start easier and more consistently in my experience, and are less finicky about fuel. Every one of my Echos starts in 2 pulls cold and 1 pull warm. Every darn time. I love my Stihl saws because of the rugged build quality (they are both pro saws), but they have random starting behavior and can be fussy sometimes. For the record, I have two Stihl saws, two Echo saws, one Husky saw, one Echo leaf blower, and one Echo powerhead with trimmer/brush cutter attachments. All four Echos start easy and reliably, to the point where it's one of the few products I can really recommend without hesitation.
I bought the Echo blower last year and been real happy with it. Use it about twice a week during the fall to keep leaves off our driveway and the 35' steps down to my pier. Over the summer I bought an Echo PAS-266 25cc powerhead ($299) along with string trimmer and brush cutter attachments. They make a real nice PAS pole saw attachment for $199 that gives an 8' reach, and a 3' extension (for total of 11') is another $49. I will be getting that next time I need to do some pruning and don't want to get on a ladder.
Anyway, it would cost $500-550 for that PAS-266 pole saw setup, and you'd be able to add other attachments in the future. You can go with a less powerful 21cc powerhead and only spend $380, but I think it makes more sense to go higher power if you can afford it. The dedicated pole saws may or may not save you $, depending on the model, and then of course you can't use the powerhead for anything else.
