Unfortunately $160 isn't much to start for airsoft. I ordered a few airguns from BuyAirsoft with no problems though I don't know about their airsofts, the link you provided didn't even provide the name of the manufacturer so I have my doubts about it. Though its rare, there have been a few guns here in the classified around that price range though even if you won't shop there, getting AV'd can open up access to the retailers who may be able to find something to fit your budget. But I would still recommend saving up more. I'm new to the sport as well and I budgeted just under $1000 for everything, I ended up spending close to $2000 and I'm still adding.
"Hey I'm the first one to say its a great country but its a straaaaange culture. This is a place where gun store owners are given a list of stolen credit cards but not a list of CRIMINALS and MANIACS. And now they're thinking of banning toy guns...AND THEY'RE GONNA KEEP THE F**KING REAL ONES!"
