I always love to hear the questions of why do you have to buy so many or why so many of the same kit. My theory is that, if you like it, you better get it now or your going to regret it later!!!!!!! I just pulled a Mercury Cyclone stock car kit off the shelf that I bought two of when they first came out and started working on it. I paid 19.99 for those kits when they were available, now they're going for 65.00!!!!! I have hundreds and hundreds of kits and yes, I'll never be able to build them all but it sure is nice to be able to have any kit that I do want to build, right at my finger tips!!!!!!!
