The recommendations for a beginner studio scale SW kit are very good ones, but I will also add a slight wrinkle to the mix. If you aren't particular about going just Star Wars, or want to perhaps try cutting your teeth on something more mainstream before diving into resin, a Moebius models classic Cylon Raider is a good dip into the studio scale pool. It is a studio scale styrene kit, so it gives you a chance to experience studio scale without going full bore into resin just yet. Plus you can practice with painting, weathering and lighting techniques on it. Sure, it is Galactica rather than Star Wars, but many of the same builders did both as Apogee and ILM were running out of the same shop in Van Nuys until Lucas took ILM north.
Second recommendation is if you haven't done a resin kit before, it isn't a bad idea to build a couple smaller resin kits first to get experience with the unique features of resin while not running the risk of potentially wrecking an expensive studio scale kit in the process. Granted the Salzo stuff is of excellent quality, but there are so many other kits out there that are not and it is always a good idea to build one's experience level whenever possible.
Anyway, just food for thought.
