I found it's possible to get unlimited blaze rods, without even visiting the nether.
It goes like this:
1. Find a couple of cinderpods in a desert, break them to collect at least 2 blaze powder. (Thaumcraft)
2. Use a minium stone to craft the 2 blaze powder into 1 blaze rod. (Equivalent Exchange)
3. Use the pulverizer to turn the blaze rod into 4 blaze powder. (Thermal Expansion)
Combining this with use of the igneous extruder to get obsidian, and turning iron into ender pearls makes ender chests pretty simple to obtain.
