Yes, there is a better way.
Today's processes use cold water extraction and micron filters. The active components of pot are primarily in the tricomes.

In the old world method, the tricomes would be allowed to dry, then they are a harder crystal type of thing, the organic material would be shaken to break off the tricomes and then the the result would be put through a fine silk filter and pressed into bars of hash. Today's TEK is pretty much the same, that's why you'll see hash bags of various sizes. PPL would start with a larger size, then keep getting smaller to get only the tricome and none of the leaf matter.
If you're still interested in oil, BHO (Butane Honey Oil) is one of the best. But be careful, don't do it inside and don't have any open flame near by.

BHO is more of a honey oil, clear, or amber, like honey. Most hash oil that is made from alcohols is rather blackish, like Jamaican Lamb's breath. It's more of a pot oil, than a hash oil.
EDIT . .. found a nice hast TEK too . . .

BTW, some PPL add a little something to both the hash oil, honey oils and hash, you can add a little vanilla or honey or some other light herbs to change the flavors.
