What type of chainsaw

What type of stihl chainsaw would you guys suggest for ripping logs in half and cross cutting a few burls? most of the logs that I have are about 600mm long the longest would be 1m long, 400-600mm at a guess and the burls 800-900mm long 350-400mm thick. Ideally I would be looking for a chainsaw under $1000. I am willing to look at other chainsaws like husqvarna and mcculloch. Thanks for any help.
Cheers WC
