You plan on cutting a bunch of wood or just here and there? The 400 series are light duty cycle saws.
That said, the 460 Rancher models are around 500 new and are pretty decent.
You can also look at Echo, they have decent saws in that range and have the best warranty in the industry. 5 years no questions asked. I have a CS410 that runs an 18 that is my go to saw for yard work. Light and powerful .
The CS450 Timberwolf is about 600 new and despite being a smaller Cc, it will run a 24 inch bar just fine
