Strats are a good kit to start with. I just completed a Strat project, and the great thing about them is that if everything lines up in your dry-fit, it's likely to go together well. Also, there are probably more after market parts available for Strats and Teles than any other guitars on Earth, so you can customize about any way you like.

For a future build (there always seems to be a next one) if you like one of the righty kits, consider asking Adam if he can custom order it as a lefty, or alternatively, if a symmetrical kit liken an SG, with the control cavity un routed/drilled. There is a lot of stuff that he can get "off the menu" as long as you are willing to wait a few months to get it. I like Jazz bass necks better than P-bass necks. Adam was able to order me a Jazz neck for my P-bass project. It took a while but was no problem.

Most people here will give you 2 pieces of advice to start with: (1) start a build diary--a great way of getting help even if you didn't know you need it ;-) (2) Do a dry fit to make sure everything fits and nothing is missing. If anything looks odd, folks on the forum will be more than willing to help, and Adam is very responsive as well.

Welcome, and have fun!
