Apeks manual C02 systems x2

I have two older haskel pump version manual Apeks C02 machines for sale. Looking to sell them together.
One is a 5 liter and the other is a double 20.
They both require to have an external air compressor.
The 5 liter can be expanded using one or both of the 20 liter vessels from the other machine.
I am asking $5,000 for both machines together.
These machines are great for small production, experimentation, terpene creation.
They are located in Steamboat Springs, CO.
Let me know if you have any questions.
