how much should I spend to get a better turntable than my current turntable?

What you’re describing is a product of turntable not being perfectly level, antiskate is not properly set and VTF isn’t right.

First and foremost, make sure the table is level - remove the cover, use adjustable feet or coins under the feet and check that it’s perfectly level using a bubble level. Only then set antiskate and VTF (use digital stylus force gauge for VTF). Check it all and test it. Play your records without the cover on the turntable. The cover is there to keep the dust away and not for using when playing records.
Second - the black lacquer finish is susceptible to scratches. Use soft microfiber cloth to keep it clean but there’s no way around it, you’ll get swirl marks and light scratches. I wouldn’t worry about it too much.
Get the set up right.

@audphile1 I did level it. That's the only thing I got right. 

If I am supposed to play records without the cover, why didn't they come up with an easier way to take it off?

Why…is it too difficult to remove the cover? Should just slide into and out of the mounts on the back. 

It does slide but it shakes and moves the the body (slightly). I will shut up and listen now.

Send it back. Seriously. Everything you say says… used, and really poor quality. Sometimes it is just best to wait, save up and get something of quality. I recommend looking at a new Rega. Send it back. Don’t justify junk.
