With turntable updates it tends to be increments and then very big jumps - the latter for things like major armboard/chassis updates, power supplies, tonearms/bearings and cartridges. Ultimately, you tend to get what you pay for.
As you spend more on your turntable though you tend to need to spend more on the rest of your system in order to get the best out of it. Matching of capability at the system level is important. So - go for the deck which best matches the rest of your setup.
