I was in your shoes and I was on the fence on getting into this sport because of the air supply aspect and then I watched some videos by airvelocitysport on YouTube. That was all it took. Very levelheaded easy to follow advice presented well. Look for his videos on the Yong Heng, the first one is like 32 minutes. Even if you don't want to use a YH it is good to get an understanding of what's involved. Just about everyone at this website wants you to buy an FX Impact and a Daystate compressor right off the bat, for your own good, but it is not necessary. If you have the cash though, it's not terrible advice. I equate it to telling a new driver, "buy once-cry once" just save up for your dream car right up front. Unless you have a good friend, that knows you very well, and is into this sport and tells you that, don't do it unless you have the money to blow. You already invested in two guns and a tank so maybe a Daystate compressor is in your wheelhouse but the equipment doesn't come with knowledge, we have to get that on our own and watching the right videos is time well spent.
