I’ve not looked at the other ships because I havent invested the time in the frigate/cruiser etc construction skills, but if you can suppliment your datacores with ’self produced’ ones it can make the barrier for entry a bit easier – buying ready copied T1 hull BPCs is fairly cheap, so the expense of the POS for copying neednt be an issue, and invention slots are available pretty much anywhere.

Basically, with the profits you make from one, you can probably finance another 2 attempts or so, so the money adds up eventually.

If youve got the construction skills needed for tech 2 ships, its always worth a shot, a hundred million spent looking into a new profit making venture is typically money well spent, and you can probably recover that in a matter of weeks if you put your mind to it, even doing things like running missions.

The profit margins on T2 frigs is not great, but it is there. You get much better profit margins on T2 cruisers, but correspondingly larger investment in materials.

Also, look into using Decryptors to increase the number of runs. Although some reduce your chances of success, the increase on the number of runs can balance it out and actually give more profit per vessel built.

Finally, a POS is not a necessary component of the enterprise. Search in low sec and quieter empire regions for stations with smaller queues on the copy slots, and get multiple bpos copying at once to spread the results out through the month. If you are going hardcore, a POS will help a lot but take that much more effort to setup and keep running, and the fuel bill eats into profits.

Oh, make sure you have the Frig Construction skill for building Tech II frigs.
