I'm looking for a Aria Pro rs-850 if anyone would be kind enough to let me know if they've seen one or have one they are willing to part with (yeah right) that would be great

Hi, Veronica.  Welcome to the forum.  Are you looking for the version with the 6-in line headstock, or the 3+3 headstock, or does it matter?
 
Bill, the guitar one

Seems she's disappeared.

I recall you have one of those Bill.
The six inline headstock that is

Hello!  
Although is was unaware of 3+3 model...Either would be perfect.
 
Thanks for the help!

The Rev Sound 850 originally had a 6 in-line headstock, similar to a Strat, but still a little different.  This was latter changed to a 3+3 headstock.  Slawie is correct, I have the original 6 in-line version in excellent condition. I don't have it listed for sale anywhere,  but I'd consider selling for the right price, or maybe a trade for something interesting.  If you click my forum handle, (Lbpesq), you can send me an email.
