Husqvarna 345 FR And Husqvarna 545 FR Brush cutter

[de3]

I'm getting ready to get into the 40cc class in a weed whipper,I own a Husky 525 and a husky 535 and a 240 stihl....I'm wanting to trade off my 240 stihl and replace it with a husky 345 or the husky 545....the only difference that i find is that the 545 has a fuel pump instead of a purge primer, and is 70 dollars more.....They say the husky 500 series weed whippers are the pro series.not sure why the Husky 345 FR isn't considered a pro series.....they both have same specs.......
