compare that with a Yamah SG2000:

£1759 at http://www.gak.co.uk

Old aria pro II were pretty ropey. I had one as my first guitar

Yamaha sg are quite a bit nicer depending on the era they are from

yeah john drummer that is the guitar that i have wanting to get a yamaha sg2000 yeah they are pretty decent guitars plumber how much do you think the old Aria Pro II is worth trying to get some sort of value if am right it is 30 years old and still going strong
