AR ES-1 table w/AQ tonearm


Hi all,
I just inherited an AR ES-1 turntable with an Audioquest tonearm installed from a buddy. First of all, is this a decent tonearm? Is there a better alternative for not a load of money? I currently run a Pro-Ject original Xpression. Is the AR better? And lastly, I need a new belt for the AR. Is there anyone that still carries parts for the AR?
Thanks

I am not sure on the model. Where would I find the model number. It looks like it might be a PT-9
I HAVE THE pt-9 AND THE ARM IS VERY GOOD BUT COULD BENEFIT FROM BETTER INTERNAL TONE ARM WIRE.
I HAVE MINE MOUNTED ON A LENCO L-75 MODDED TABLE AND IT IS A VERY GOOD ARM FOR THE MONEY.
AQ ALSO MADE A LOWER PRICED PT-6 ARM.
NOT SURE WHERE THE MARKINGS WOULD BE MINE CAME WITH THE BOX AND TEMPLATE.

fOR YOUR STOCK AR TABLE THE AQ IS A GOOD ARM I DONT THINK BUYING AN EXPENSIVE ARM FOR THEAT TABLE WILL YEILD ALL THAT MUCH SONIC IMPROVEMENT WITHOUT MODDING THE TABLE ITSELF
