Stop, buying Kits. NEVER.
Shudders, sits down and pops a brew to calm the nerves.
I might slow down so that the storage can be emptied a bit for NEW kits.
Me and my Wife got an agreement, I shop at the Plastic Model Floor she shops in the patchwork/quilt section.
Display space & storage is fought over with either me holding a pair of scissors & her cut cloth and her offering to beautify my work-bench with the gas-torch.
:D
Actually we get well along, unless she starts to dig in my tool-box for handy tools. OTOH, she made me a portable tool-roll for competitions and so on.
