What is your goal? The Elemental is a USB table. This means it not only has a built-in analog-to-digital converter (ADC), but also a built-in phono preamp, so you can plug it directly into any standard line level preamp. Do you need these things or are you better off spending your money on more turntable and less on preamps and converters?
Speed accuracy is important to a good LP playback experience, but it's not the only thing, and .13-14% isn't bad. The Elemental is $275; how much is the Technics SL1800 and what is its condition?
Each turntable has its own merits; direct drive turntables have a pretty low noise floor, excellent speed accuracy (if the spindle is lubricated and everything is in good working order) and has a strong, rhythmic drive with an assertive midrange. Belt drive tables with elastic belts such as the Element tend to have a more laid back presentation, perhaps not as driving or compelling as a DD when the music calls for it.
It's also helpful to know what preamp/amp and speakers you'd be plugging this into.
