PRO saws are nice but cost a lot more. The 290 is a proven workhorse and just lasts. The 391 is also a very good saw. I have run a 310 with a 390 piston and cylinder for a while and have had the 310 for 15 years. It is another that just works.
Not everyone needs to have a PRO saw for their firewood cutting.

Sort of like the guy driving around in a dually who bought it to tow a 17' fishing boat.
If you want nice toys, buy nice toys.
If you buy nice toys to impress others, that doesn't impress me.
