Poleaxe flares are fun and quite rare, and once the weighting is gone you could enchant it (and up to +20 can be a side project). You'll do better than 35k. 100k? 1m? I don't know. For stuff without a lot of comps (e.g. 7x fusion) it's just a matter of lucking into auctioning it off when at least two people are interested.
