Well you said it yourself that the MS290 handled your needs nicely. That's what I have and unless you just deal with bigger wood I can't really see the reason for much bigger. You can find MS290's used in good condition really reasonable. Bar length will probably factor in to pricing a bit. But with that model being so widely sold for so long there will be parts around for it for a long time. Online or at dealers. That's a solid bet. But get what you like and what fits the budget. Good luck and post a pic of what you get!
