I've been wanting the Mace and double Maul forever. Just need to wait for a deal. THought I had own with tfaw but kinda scared now.
You can find double Maul FX sabers on ebay now and again for $120 Buy It Now prices. The shipping is usually about $20 or less. Considering that I paid about $160 for mine when it came out, that's not a bad deal.
One thing to keep in mind though is that this really is a BIG saber when it's fully assembled. I've gotten to the point where I only combine them for special occasions. I've been looking for a damaged one that someone is trying to get rid of so that I can disassemble the blade and just use the hilt to create a single-bladed, full hilt version of this. Haven't come across one yet...
Good luck on your hunt!
