The first site I found, I got my ass handed to me. It was a very hard site and me, being the stubborn creature that I am attempted to do it. I failed.
I got the great idea to kite the NPCs away from the cans and attempt to hack them.
Much to my delight, it worked.
The first can revealed two skill books. I didn't check on them immedately but later, I did to the tune of 100 mil isk in skillbooks. One was Drug Manufcaturing. The second was Neurotoxicology.
Second site found Nanite Control and Neutrotoxin Recovery as well as Standard Sooth Sayer Booster Reaction.
There are random datacores that I will just shove into a container for a while. Maybe I can dump them as a lot in Jita eventually.
Later that afternoon I wandered to another system a few jumps away and proceeded to hunt down another 3 sites each with data cores and smaller stuff plus a mag site full of salvage with a few t2 salvage bits. Another jump over led me to a Magnetometric site and more salvage. I wound up having to use all of my exploration tools through all of the sites and I've developed a lovely kiting method to deal with NPCs to big for me to shoot.
I'm pleased with my haul. All told I made about 200 mil. If I had sold the one skill book on the market that would have been 450mil. I also have 95mil in buy orders sitting on the market so really I made about 300 mil (once the items sell). I've not made that much in one day before on my own. They are not the sites that drop the type A things that cost a bil isk a pop, but I don't think its that bad for me, just after my 4th month.
I am very excited. I also harvested some gas yesterday. That 15 or 20 minutes of gas harvesting while I was getting ready for work netted about 3mil isk.
The biggest question is what ship to use to do these sites. It has been suggested that I get a cynabal but I'm not sure that I want to start working with a 200mil isk ship (for just the hull) quite yet.
