Why soooo many planes???
Well I geuss Im the lucky one here,I just recently picked up the hobbie and my wife doesnt complain.
We made a pact when we got married ( 8 years ago ) to disscuss any thing we purchase over a set amount of $ ( ours is $100 ).
That is to say I can buy anything I want as long as its under $100 at a time and she can do the same.She buys nascar junk and I go to the hobby shop.Man can you get a lot at the LHS for under $100 and anything over I need I put on layaway so she only sees the smaller bills.
Maybey you could try some sort of pact.
