It may be worth while to check that the saw you decide on runs .325 pitch chain, a lot of the smaler consumer saws run 3/8 low profile or extended pitch chains. I think a .325 chain has more to offer.
Another consideration that may factor in depending on your area is it is often near imposible to get service or parts for saws like poulan, mikita, craftsman, homelite ect.. Where if you have a Husky, Stihl, Johnserd (a saw from a dealership) at least there is somewhere you can take it to have it serviced by a manufactures rep.
In the so called brand name saws it may be more importaint to have a quality dealership / service centrer near by than to have the absolutly best quality saw.
one of the saws im using is a Stihl 260 and like it, but by what you described the 260 would likely be more than you require, an 025 might fit your need well. The 025 won't cut as fast or last as long, but it would likely cut all the wood you'd burn in a fire place for 10-20 years (maybe more).
Price might be competitive on a 345 husky or 025 stihl.
The husky 141 or stihl 021 are smaler and use lo profile chain, the Husky 346 and Stihl 260 are higher preformers but will cost you more.
