How many fill sources do you have? I started off like many with a handpump. VERY soon after that, I decided to get a portable compressor (hatsan tactair volt), but quickly realized that it wasn't as handy as I was really thinking it would be. So then came the purchase of a tank (74cuft AV). As good as this was,I very soon grew tired of a 30 mile one way trip to the paintball supply. Then came the yong heng...pretty quick fills from the convenience of my garage. Not sure how long it take to get tired of the bucket/ice water, oil changes and air filters, but for now, I think I'm done with buying air supply stuff. But this seems to be a neverending quest for convenient air sources. Boring rant over.
