I believe the 066/MS660 is about 90CC, and slightly larger than you specified. But that would be my recommendation. They will pull .404 chain, but I see .404 being used mostly in soft wood, like pine, fir, cedar, etc. You can accomplish basically the same objective with an 8-pin sprocket and 3/8 pitch chain. I believe parts availability for the 066/MS660 will be excellent for many, many years to come. Lots of custom parts, like dual port muffler covers, lots and lots of bars and chain available. You may pay a little more up front for an 066/660, but I believe it would be a far better long-term investment, unless you just have an urge to own a 'classic saw'. In that case, for me personally, I would consider an older heavy Stihl, like the 051, 075, 076. 070, 090. A lot depends on whether you want a saw to work with, or one that is more of a compromise between a working saw and a collector's item.
Bottom line, I say, save a few more bucks, and buy an 066/MS660. In my case, I prefer the older 066 models. If you have your heart set on a Homelite, the folks here are saying very good things about the 925. I see a lot of this model for sale on Ebay, so parts availability should be about as good as it gets for an older saw. I have seen a few nice 925s sell for less than $200.00. It's about a 5 HP saw.
