I'm finding that building/repairing stuff helps fill some of the GAS void.
Or in my case, the financial one! I love to fix and repair things. For as long as I can remember I've dabbled in electronics and I am a pretty decent woodworker, but it wasn't until I starting wanting gear that cost way too much money that I started building or restoring guitars and pedals. And yes... it keeps me buying guitars and pedals. But I still want them!!
