You did quite well for $650 including 600rds.
For comparison, I just bought 1000rds of WPA ammo for $350 a few weeks ago, so thats $175 for 500rds (say ~$200 for 600rds).
So you got the rifle and mags for $450, that is a good deal IMO! Mags are around $20 a piece depending what and where you buy.
WASR 10's are decent rifles in my experience. I have a 10/63 with the folding stock also, very accurate even with just iron sights when properly sighted in. Congrats and happy shooting!
On a side note, we will never see true pre-panic prices; those days are gone so get used to it. The combination of Inflation, bad economy, and the fragile state of the gun culture is to blame.
