Well $150-200 for an metal AKS-47 Reciever ( might be able to get a plastic one on classifieds) $150-200 on a AK platform to build said gun from.
you might be able to save a bit of money if you manage to buy a AK-47 front end, mechbox and bolt/ dustcover separately on the classifieds)
If you do not buy a wood kit and instead use plastic furniture you save another $100.
If you are lucky you may be able to build an AKS-47 for 200-250$. I built a plastic AKS-47 on the cheap for around $250 2-3 years ago.
You will quickly find out that a lower end parts will start to give you problems the folding stock kept falling apart the mechbox down quickly. Apparently it was worse then a CYMA mechbox.
If a $300 Asia electric gun is too much maybe you should just Buy a Kraken AK-47 full stock ( CYMA AK-47) and paint it black or a Beta Spetz they seem to go for around 200$ and up on many retailers.
