Dual 721 turntable - opinions/advice?

I just picked up a Dual 721 for under $20. Seems to run fine. Looking at the strobe, it looks like it is maintaining speed. It has a "supposedly" new AT120E cartridge. Maybe new 20 years ago? Dust cover is thrashed.

I thought I might have someone put new RCA cables on it, a little oil on the bearings, and put my Sumiko Pearl cartridge on it.

• Any advice? Thoughts?
• How does this TT compare to others?
• How does this compare to my Akai AP-Q80 direct drive TT?
• Any ideas where to get a dust cover in decent condition?

Thanks,
Craig
