Extraction Experts Products?

I ordered the "X3 Stainless Steel" set last night, if anyone who doesn't know what that is. it's 3 stainless steel tubes with a rubber stopper that holds up to aprox. 60 grams. I spent $130 on this product. This set comes with a tripod that holds all 3 tubes.

Now today, I just did a little bit of lurking and found that they sell "Closed Column pressurized oil blaster" which lets either blast open or closed. It seems like I rushed my order a bit and should have gone with this product instead. -

Can anyone shed some light and weight the differences between these two products.
Yields, marinating the marijuana, all around differences?

The X3 system doesn't have an outlet valve. You would blast and collect all at one time. The closed column has an outlet valve so you can steep in your solvent before release to collection. Weight differences would be negligible. You could always blast another can in the x3. The closed column might marinate some extra chlorophyll, that you might not want. You could blast the closed column open and that would be functioning like the x3. The closed column is more versatile.

@warble I was just a little bit worried about my yield, and I'll pass on the chlorophyll. So really not so much of a huge difference, I would think the end result with a closed loop column would produce a much more nicer oil in terms of purity and potency.
