I can't recall what I paid, its certainly not a wallet breaker though.
Here's what I put in it:
systema silent head set
guarder clear hopup rubber
systema spring guide
systema shims
and a stock CA spring (about 310fps as I recall)
The barrel is still stock, but seeing as how I get ridiculous range on it at 310, it's a prime candidate for a TK twist barrel

Silencer actually makes the gun a bit quieter too!
