Upgrading a KJW or Tanaka are pretty simple. You'll spend $100 on just the magazine upgrades if you don't shop over seas. I would buy it used and I would not get the take-down model since it's advantages are only useful when you are off the field. I think their is less to go wrong in a gas rifle then their is to wrong in a spring rifle but you'll end up spending about the same if you get am air rig or a laylax zero trigger. But, the air rig can be used on multiple gun unlike the zero. Fun project gun. Focus on you hopup and buying everything used. I did mine for CHEAP. I think I put in about $200 and had it valuing somewhere around $5-600. The PCS bolt version of the Tanakas are pointless if you convert the magazine to HPA. You regulators will do a better job than the flow restrictor ever could in the bolt. And once the HPA is regulated the PCS does nothing.
