Vortech V-2 or V-3?

[Cookbot]

So V-2 or V-3? They're both the same price, but the later won't need a deep sump for more oil as it's all contained within, or is there more to it than that?

Pros and cons to both. V3 is self contained as you said, and therefore won't require you to tap your pan. However it does require you to change oil at certain intervals (and check it with the small dipstick thing) and they recommend Vortech's own for the job, unsurprisingly.

 

As far as I can tell the actual compressors are the same though.
