Although be aware that if you're not careful the hobbyist engines can explode. This happens if the engine runs dry, and you try to refill it while it's still hot. Easily avoidable, but still quite a nuisance. You may want to look into hooking up an Aqueous Accumulator, if you've already got gold and redstone for the hobbyist engines. (Although finding cacti for waterproofing is really quite annoying, and setting up an Apiary and a Centrifuge for beeswax requires quite a bit of bronze...)
I think there's a guide somewhere for MJ 'tech tiers'...
