After all my reading I have decided to do the same thing. I just ordered a 74 ci ft tank from Top-Gun Airguns. That's what Ill be topping off. BTW I bought a GS Pump CS3. It didn't even last through the testing of just filling up the filters. Sent it back to Amazon. On to a Yong Heng. Thank you for your feedback.
In my opinion the key to the Yong Heng is keep long runs to a minimum, mine are usually only 15-20 minutes, and keep it cool. I use a Homer Bucket with water and "Water Wetter" and run the water through a 3-fan computer radiator. My temps never go above about 55 degrees centigrade. One of my deciding factors was that I could buy 8-10 Yong Hengs for the price of the Coltri. Good shooting, good luck, happy days, and above all GOD BLESS TEXAS!
The problems with this scenario is that in the end you've incrementally paid the same amount as on a dive compressor and just accumulated 8-10 broken compressors with zero residual value. In addition, it takes time setting up buckets, repairing frequent breakdowns, spending money and time waiting for parts, etc. It's worth a user's peace of mind to just turn on a reliable compressor and seven minutes later have a full SCBA tank of dry air. For example, a 4 year old Alkin is worth more used than it originally cost due to inflation and price increases. Even sold at a loss a dive compressor is a bargain in the saving on migrane pills. Plug and play is worth it not having to plug and pray.
I agree the Tuxing twin is a good buy. I bought a TXEDT033 which is an 032 but with "auto purge" thinking it was truly an auto purge system, which it isn't. All it does is release air at the end of the fill cycle - it doesn't purge moisture as it builds up during operation. That being said, my disappointment was with Tuxing Official Store, not the compressor itself. The 033 arrived damaged and Tuxing was unwilling to replace or refund. It was only once I got Amazon involved that it was settled - and it literally took months - about four months - to get it resolved. I think this link will take you to one of my reviews which I posted on several product pages for Tuxing. Afterwards they tried to bully me into changing my rating and review.The Tuxing two cylinder compressors are really in the same category as the Yong Heng. You're paying for the add-ons that make it more convenient to use. I got the 032 only because it's a self contained unit with cooling system and filters onboard, so I don't have to constantly mess with buckets, fans, and hoses or invent my own cooling system. Other than that, it's basically the same quality (a hit or miss). It's just as easy to service though, and parts are available. The filter design is meh, needed some improvements there. But it works. Runs quieter than the Yong Heng so that's a good thing and the cooling system works, too. Overall, it's a decent unit for the money, but no longer disposable, so you do need to be prepared to fix it when it breaks.
Alternatively, if you want to go the disposable route, you could probably keep the enclosure with the control unit, cooling system and filters, replace the compressor itself with a Yong Heng, and just keep swapping it when it breaks
This right here is spot on the truth.
