Unless you buy used, the TS-590SG is $1,400. More in line with your budget is the Icom IC-7300 at $1,000 new, after rebate. I've had many radios in my 62 years as a ham, and primarily a CW contester.
I presently own two 7300's in SO2R contest configuration, and find them as good a performer for 95% of my operating as any radio I've ever owned. The DSP filtering is continuously variable down to 50Hz, giving you great rejection of close-in signals. It has the latest SDR technology, and the built-in panadapter/waterfall is, to me, essential in any modern day radio...something the TS590 lacks. The newer Icom radios are (free) firmware upgradable, so the idea that they constantly come out with new models really doesn't apply anymore.
The TS-590SG is an excellent radio, but seemingly out of your budget range, if buying new. Just my experience and opinion. Good luck with whatever you decide on.
