Refrigerators are $6K, that's basically nothing for an essentially permanent object that you need.
It is, however, a slightly difficult acquisition when your liquid assets amount to a little over $3.5k. Yes, I really do hate blackjack right now.
A note about the clubbing nerd that Fritz detailed is that clubs are remarkably versatile. If your third stat is Brains, you can hold up your end with medical assistance, hacking, repairing, crafting, and even the occasional bomb. If you pick Senses, you get crafting again, plus a bonus to dodge, scavenging and tracking. You even get an extra bonus to throwing, which I've heard can be quite useful under certain circumstances.
And if you pick Cool as the third stat, you've got the triumvirate of gun-based stats. Brawn, Reflexes and Cool. At that point you may choose to be a knife user instead of clubs, but clubs can still be used well and they're not bad weapons overall (from what I can tell). I still have no idea why a
sagebrush is supposed to melt people, but I guess that's just my ignorance talking.
I actually hadn't even thought about taking Yeti Fur on this character... But the cold brains bonus might be handy, and it's always good fun to bunk out in a place that other people have great difficulty with. But I am a bit cautious about the penalty to being in a warm place. Might have to take Chiller as well, then I can even preserve food without a cooler, which is an added bonus. An added-added bonus would be that it mitigates the Cool penalty of snagging Swollen Brain.
At the moment I've got 3-4 mutation slots and nothing in 'em. Been a little unsure how to proceed on a number of fronts.
