I have a stock 575........ 24 or 28" bar, if you want it...rebuilt by chainbar.com $425...or PHO........... $350....prices flexible, up..or downnnnnnnnnnnnnnnnnnn plus shipping.....
Yes most of my work will be done with 20". Occasionally need a bigger bar. But mostly firewood in log length 20" is plenty. I've got a tired 029 and now the 550xp makes the 029 seem like slow motion. Luckily I can borrow a 575 most of the time but it would be nice to have a little something to call my own.
If you are mostly bucking firewood I would go for a Husky 365/372 special/XP/XT, cheaper, easier to mod, parts everywhere, really clean used ones around for under $500 all day everyday.
