just waiting on the PCP. It seems the cheapest are about $500 and I would prefer to wait to get a decent one.
Don't forget, you'll also need "support equipment" for a PCP. Either a fill tank or some kind of pump.
If you're going to be shooting in your basement for marksmanship practice and recreation, I'd HIGHLY recommend sticking with .177. You'll get a lot more shots per fill than with a larger caliber like a .38, ammo will be a lot cheaper, your target backstop will be a lot simpler to construct and will last a lot longer and the airgun will likely be much quieter to shoot.
