Well this is my 3rd major Hobby
First came photography and $25000.00 in gear... I thought Holy crap... at least I am shooting about 20 weddings a year to cover that hobby...
Next came Airsoft.... well there goes another $10,000 in gear guns etc...
then came the Phantom Vision... (well it's almost here) - Christmas Gift. it starts at $1199.00 and well the sky is literally the limit right... Hell I can't even use my new hobby until April.... Currently in Winnipeg the temp is between -4 F to -22 F Fricken BRRRRRRRRRRRRRRR
