Thanks for the additional information, it fills in the story of how you came to be where you are. Yes there are certainly higher quality tables than the Rega or the Kenwood. This is a vintage site and there is a lot of love for the classic Kenwood direct drives, however its not an opinion I share, so my thoughts will go against the flow of what is generally accepted here at AK. Take what I say for what it is, just an opinion.
The heart and soul of a turntable is the quality of the bearing, and a motor that operates smoothly with as little vibration as possible. The whole goal of the table is to minimize resonances from the operation of a mechanical device, as the cartridge will pick up those rogue signals and it will compromise the information the stylus pulls off the record. Now motors do not have to be huge and have tons of torque, but rather just need to keep a steady speed with minimal vibration. A heavy platter will actually work in conjunction with a smaller motor to create a very smooth drive system. The question is which drive system do you think works the best for you? Belt drive, direct drive, or idler drive?
Then the quality of arm comes into the discussion. In many cases you will find that the integrated arms on a table can be of middling quality. The arm can be a cacophony of resonances due to all its sub parts and bearings. Getting a quality arm can be expensive, especially when dealing in the arm only market. That is the calling card of your Rega, a good quality arm at a reasonable price. It is what outshines the rest of the table, and its limitations are its sub platter which can often be noted to be a slightly incorrect circumference and result in incorrect speed.
You mentioned VPI and the used market. Personally I would save money until you can take on a deal such as this one. Yes its more than you budget, but there are some other alternatives also.

This one is sans arm. By the time you find the arm it probably gets to be as expensive as the one above.

If you are content to listen to one of these tables, keep it around and sell the other and build up the audio kitty for a table that meets your bar for performance and quality.
