LOL..! Nice Spike. Most I have ever been able to pay for a kit was $50.oo for a sealed Ertl International Eagle semi truck kit but I made good money back then and could afford to buy it...wish it was the 4070A kit though.
I kind of feel the same way as you do on this....I build to make myself happy but I do try to make them better as possible each time I build one. I do collect a few but many end up getting built in time or traded off for others Id rather have. Building gives me something to do to pass all the time I have besides I love it anyway....maybe its just the challenge of it all...?
