Sorry to break it to you, but Tokyo Marui guns are very hard to find wholesale because of their great quality. Also, the abay market of high-end airsoft guns is fairly exclusive. You'll have to invest quite a bit of money in order to make a good return. The only good way to get TM guns for low prices is to buy it from overseas, but then you have to deal with importing which is a hassle. If you're no stranger to importing, then go and search for overseas companies and BUY IN BULK. Thats the best way to make a good profit with higher end airsoft guns. I think that you will have a much easier time buying lower-end airsoft guns because of the pricing and availability. And on top of that, people buying airsoft guns on ebay (if thats what you'll use to resell) generally aren't looking for top of the line guns, they're looking for cheaper guns that sellers present in such a way that makes them look like the are amazing guns. I hope that this has helped in some way or another. If I lost you in my post, feel free to send me a message and I'll try to help you out.
