Yeah a good roasting machine is pretty expensive.
To be in the roasting game in this town you pretty much have to go to the farms you buy from, meet the farmers, watch the plants grow and smell the manure. If you just buy beans from some commercial distributor and roast them up without sitting at some farmer in Peru's table you are a chump.

The second one has energy, the first is fat. Go with the second one.
I'd go with one of the first two. I don't like the W on the third (too big), the fourth looks a bit cheesy / cheap and the fifth has a really irregular font. Do add the chip-in from the original, where the V overlaps the E, but on the first or the second logo design.
