AGR Energy has recently released a smaller version of the BioPro's. It's called the BioPro 150.

It's smaller in size and makes 40 gallon batches. Price is significantly lower too. MSRP is at $5995 + Shipping.
The major differences between it and the BioPro 190 are
1) Smaller Batch Size (40 gallons instead of 50 gallons)
2) Removal of the automated water out system (you drain it manually after each wash)
3) It utilizes a single tank for both methanol & methoxide
4) The fuel filler pump is available as an option but doesn't ship with it in stock form.
5) Instead of sight-glasses, it utilizes tank gauges, which work great!
The machine itself still does an automated processing & automated washing & drying but after each wash you manually drain the water out the bottom port.
In every other way, it's still a robust BioPro. Still made from high quality Stainless Steel & high quality materials, pumps, and other items. It's a really robust machine.
Warranty is also the same as the others as well.
1 year parts & labor.
