The bags are definately the best way to go. I used to do the oil thing but since I picked up a set of bags that is no longer. The hash you can produce with these clever devices is the most potent and tasty stuff around. I actually enjoy it more than the best buds off the plants.

If you are into gardening or have access to a lot of trim, it is well worth the investment. There are a number of sizes available - 1, 5 and 20 gallon. The 1 is totally useless. The 5 is about perfect for the average person. You can easily yield 1 oz of dried hash per run. The 20 gallon is for the mega producer - makes me drool thinking about how much it would produce.

I have a 5-gallon set I purchased online from www.resinextractor.com. They work great for me and I have used them quite a few times now. $100bucks for a 3-bag set.
