Thats what I use, but if the gamerz haven't permeated the ebay firearm accessories market, I would suggest not cheating the auctions there. If you buy PC accessories or it seems anything else, using that is a must, IMO.
Make sure to use a bid sniper; I use this one from my phone. It lets you bid at the very last second for the minimum possible value so you don't get caught up in bidding wars, don't pay any more than you originally intended, and don't stress so much about winning the auction.
And $150 might actually be a little high- with the bid sniper, I snagged a mark 2 for ~$175, although the seller told me he had sold it on craigslist instead, so I ended up waiting some more and picking up a second hand push 1.
